Introduction of the Project:

The Taitung Line is the southern section of the Eastern Line of the Taiwan Railway Administration.This line starts in Hualien and ends in Taitung, thus its name the Hualien–Taitung Line (or the Hua-Tung Line for short)

It is 161.5 km long, including the main segment of 155.7 km between Hualien and Taitung.

The coastal branch lines of Hualien and Taitung have been discarded after the bordening plan in 1982.

The north segment from Hualien to Tamasato (now Yuli) was built in 1909 and completed in 1917. The south segment form Beinan (now Taitung) to Lilung(now Guanshan) was opened in 1919 by the Taitung Development Company.

In 1922, the Taitung Development Company bought the railroad from Hualien to Yuli and called "Taitung North Line", and the south segment of Beinan to Lilung called "Taitung South Line."

The connection railroad between Yuli to Lilung was built in 1921, and completed in 1926 which the total length was 171.8 km from Hualien to Taitung.

In 1966, the Guanghua Train (Diesel Multiple Unit,DMU) started to service in this line and shorten the traveling time greatly from 6–7 hours to 3–4 hours from Hualien to Taitung.

Its gauge was changed from 762 mm to 1067 mm in 1982 and connected with North-Link Line and discarded the old Hualien Station to the new place which the Hualien Station is located now.

In 2007, the Environmental Protection Agency (EPA) gave the line a conditional pass for an electrification project, which will boost the operating speed of the line from 110 km/hr to 130 km/hr. In 2009, construction began on electrification work, with NT$15.5 billion set aside for the project. Electrification work is expected to be completed by 2013. An additional NT$6 billion has also been allocated to renovate stations along the route.

The Project installed 35 pieces of our GPS NTP Time Servers to Synch time for Substations.

IEC61850-The Future Protocol of Power Automation

The current in the power system, more and more high to the requirement of substation automation, for the convenience of all sorts of IED in substation management as well as the interconnection between equipment, you need to implement a common communication way.

Introduction of IEC61850 put forward a kind of public communication standards, a series of standardized, through to the equipment to form a standard output, to realize the seamless connection of the system. [1] IEC61850 standard is based on the general network communication platform of the substation automation system is the international standard, it is by the international electrotechnical commission 57 technical committee (IECTC57) three working groups of 10 final three (WG10/11/12) is responsible for.

This standard reference and absorbing the existing many related standard, which mainly include: IEC870-5-101 telecontrol communication protocol standards; IEC870-5-103 relay protection information interface standards; UCA2.0 (Utility Communication Architecture2.0) (set by the U.S. electric institute system of substation Communication protocol and feeder equipment); ISO/IEC9506 manufacturer information Specification MMS (Manufacturing Message Specification).

Substation communication system IEC61850 substation communication system can be divided into three layers: substation layer, spacing layer, process.

In substation layer and intervals between the network USES the abstract communication service interface is mapped to the manufacturing message specification (MMS), the transmission control protocol/Internet protocol (TCP/IP) Ethernet or optical fiber net. In the interval between the layer and process layer network using a single point to multipoint Ethernet one-way transmission. Within the substation intelligent electronic devices (ieds, measurement and control unit and relay protection) adopt a unified agreement, exchange information through the Internet.

The characteristics of the IEC61850 is 1) object-oriented modeling; 2) abstract communication service interface; 3) for real-time service; 4) configuration language; 5) the whole power system unified modeling.

IEC61850 modeling the most public actual devices and components. These models define the public data format, identifier, behavior and control, such as the transformer substation and feeder equipment (such as circuit breaker, voltage regulator and relay protection, etc.). Self description can significantly reduce the data management cost, simplify the data maintenance, reduce system downtime due to configuration error. IEC61850 based power system set up as a seamless telecontrol communication system can greatly improve the data integration of information technology and automation technology equipment, reduce the quantity, site acceptance, operation, monitoring, diagnosis and maintenance costs, save a lot of time, increase the flexibility of the during the life of the automation system. It solves the substation automation system interoperability and protocol conversion problem. Adopt the standard also can make the substation automation equipment since the description, the diagnosis and the characteristics of Plug and Play (plug-in and Play), great convenience to system integration, and reduce the engineering cost of substation automation system. In our country, using the standard series will greatly improve the technical level of substation automation system, improve the level of substation automation system safe and stable operation, saving development acceptance maintenance resources, to achieve full interoperability.

2 characteristics of IEC 61850 standard IEC 61850 standard is by the International electrotechnical Commission (International company technical appointed the 57th technical committee issued in 2004, the application in substation communication network and system of International standards. As based on network communication platform of substation, the only international standard IEC61850 standard absorbed IEC60870 series standard and the experience of UCA, at the same time to absorb a lot of advanced technology, the protection and control and other automation products and the design of the substation automation system (SAS) produced profound effect. It will be not only used in substation, and will be used in substation and between control center and control center at all levels. Major power companies and research institutions at home and abroad are actively adjust the product development direction, and tries to new international standards, to adapt to the development direction of the future.

IEC 61850 series standard of 10 categories, 14, name is not here, readers can easily find on the Internet, to introduce the following main characteristics of IEC 61850.

(1) Defines the information hierarchical structure of the substation

IEC 61850 substation communication network and system agreement draft standard puts forward the concept of substation information within the layered, substation communication system can be divided into three levels, namely the substation layer, spacing layer and process layer, and defines the communication interface between layer and layer.

(2). Using the object-oriented data modeling techniques

IEC 61850 standard USES the object-oriented modeling technology, defines the data model based on client/server structure. Each IED contains one or more servers, each server itself contains one or more logical device. Logic device contains logical node, logical node contains data objects. A data object is composed of data attribute public data named instance of a class. In communications, IED also play the role of the customer. Any a customer can be abstract communication service interface (ACSI) to access the data object and server communication.

(3). The data from the description

The standard defines the device name, logical node name, instance number and the name of the class data to establish object name naming rules; Using object-oriented method, defines the communication between the service object, for example, to get and set object values communication service, obtains the object list of communication services, data object value list of services. Object-oriented data since the description of the data source to the data itself to self description, data is transmitted to the receiver with the self, don't need to for engineering data quantity, scale conversion, etc. Because the data itself with instructions, so transmission can be defined in advance without limit, simplifies the data management and maintenance work.

(4). The network independence

IEC 61850 standard summarizes the necessary communication services, information transmission in substation was designed independently of the network and the application layer protocol used by the abstract communication service interface (acsi). In IEC61850-7-2, established standards compliant server must be provided by the communication service model, including the server model, logical device model, data model, data model and logic node set model. Client by ACSI, and the specific communication service mapping (SCSM) mapped to specific protocol stack, such as manufacturing message specification (MMS), etc. IEC 61850 standard using the ACSI and the technology of SCSM, solved the stability of the standard and the contradiction between the development of network technology in that when the network technology development as long as the change of SCSM, without the need for a modified ACSI.

Three series of IEC61850 standard IEC61850 series standards contain 10 parts:

IEC6l 850-1 basic principles;

IEC61850-2 terms;

IEC61850 to three general requirements;

IEC61850-4 system and project management;

IEC61850-5 function and device model of communication requirements;

IEC61850 substation and feeder equipment - 7-1 basic communication structure principle and model one by one;

IEC61850-7-2 basic Communication structure of substation and feeder for each Abstract Communication service interface (ACSI: the Abstract Communication service interface);

IEC61850-7-3 basic communication structure of substation and feeder equipment level of public data one by one and properties;

IEC61850 substation and feeder equipment - 7-4 basic communication structure of compatible one by one logical node and Data objects (DO: Data 0 bject) addressing;

IEC61850 an 8 specific Communication Service Mapping (SCSM: Special Communication Service Mapping) : in the transformer substation and spacer layer and substation layer and intervals between Communication map;

IEC61850 is a specific communication service mapping: within the interval layer and process layer and layer and process of communication between the mapping between;

IEC61850 10 conformance testing.

Shanghai Electric has successively built nine overseas projects,which accounted for nearly 20% volume of their turnover.

In the northwest of the Indonesian resort island of Bali, a group of employees from Shanghai electric power construction co., LTD are busy with the construction of new power plants. Scheduled to be completed next year of the first phase of Bali, Indonesia to 3 units of 142 mw coal-fired power plant project, Bali is a standalone capacity, with a total installed capacity are the largest coal-fired power plants, as the "green heart" vacation paradise.

Jiang Lindi party secretary of Shanghai Electric company, since 2009, turbine construction in Shanghai waigaoqiao power plant phase iii, caojing power plant a few million kilowatts units such as engineering, for three consecutive years won the highest honor in China construction exposition, the national high quality project, by the end of last year, 36 project of Shanghai turbine have been awarded the international power station respectively, the Asian power gas power generation project gold medal award for the best, national quality engineering exposition, etc.

In spite of this, international business from domestic project transformation, there are still many difficulties to overcome. Laos HongSha total installed capacity of 3 units of 626 mw power plant project, Shanghai turbine for the desulfurization system, chimney, and all the circulating water system, such as cooling tower, there is a three tube chimney, three cooling tower, such as high-rise buildings, large volume, high quality requirements, the construction is difficult. "Such as yellow sand and gravel, not worth of supplies at home, here have become important factors of restricting the progress." Project manager Shi Yaohui introduction, gravel 40 kilometers distance from the scene a stone factory, transportation time to 3 hours; Yellow sand 53 km distance from the scene of the Mekong river, transportation time to 5 hours, every year in May - September rains and can't provide. So, procurement staff deep into the mountains for many times, looking for new sand source and Shi Yuan.

Bali again project, here scenery charming, but carry out the construction of infrastructure is a challenge. "As a world famous tourist destination of Bali, if the environmental damage caused by the construction, influence is very big." Project manager Huang Xiaoming tells a reporter, Shanghai turbine engineering before the implementation of environmental protection measures for the detailed planning, big to construction technical plan formulation, small to life, the processing of construction waste. Take the project the dining room, the only change in the past, in the form of coal as fuel and use bottled gas this one, is spending 1 million yuan more for this cost. The Bali tourism is given priority to, lack of industrial base, construction equipment, steel and general construction materials shall be from the outside into the ocean shipping. Overseas supplies as much as possible in order to control cost, project staff went around near the city's main building materials, machinery market, research inquiry, to carry out the supplier, sometimes to a little spare parts to take several days to find.

In the next 3 to 5 years, Shanghai Electric will continue to play is located in Shanghai's location advantage and internal advantage such as technology, management, talent, further expand overseas market, strive to five years, the international business proportion to rise from the current 20% to about 50%.

Encourage investors to construction of IPP and BOT power plants. By 2010, Vietnam is planning to build 32 EVN power plants and 89 IPP, BOT power plants, a total investment of about $10 billion.

3. Vietnam electricity technology needs

Vietnam electric power development at present the main problem is: in northern Vietnam electric capacity shortage; Load the rapid growth of demand; Big peak valley difference; Power grid reliability and stability of the problem; The power supply line loss is bigger; The large capacity power problem; International coordination problems (with China) connected to the technical standard, and the corresponding control measures.

Vietnam electricity technology needs mainly include: improve the level of power grid, power plants, substation control standards and, if establish unattended substation, etc.; Need to analyze the development and operation of the whole system and research; Set up a corresponding technical standards; EVN prepared to set up some research institution, to research the problems in power system, is the preparation of the high pressure experiment, the need for technology and staff training; In 2010 in central Vietnam planning in nuclear power plant construction, the cultivation of the technical cadres, training and financing aspects of the work is under way.

Vietnam in electric power construction, many problems existing in the production and operation, is an urgent need to communicate with experts and technology of China, learning experience and technology of China.

4. Pay attention to and to solve problems

Vietnam is a country with a developing rapidly in recent years, the economic growth rate is higher, electric power development speed is faster. Vietnam national and EVN are ambitious to the development of electric power, full of confidence and hope in all aspects of the electric power construction. In addition to electric power construction and operation, but also very concerned about communication, information, manufacturing, technical research and development and so on many aspects. But in the process of development, Vietnam also faces many problems need to be solved and difficulties, including financing, the construction of the new project, security and stability and economic operation of power system, such as the technical problems in technical cooperation for the power system in China and Vietnam have created good conditions and output.

Vietnam is an urgent need to solve the problem of long distance transmission of power grid stability. Vietnam has a north-south 500 kv lines more than 1500 kilometers long, is building another 500 kv lines more than 2400 kilometers long, its frequency and voltage stability problems will have to face and solve.

Vietnam is an urgent need to enhance the level of its electric power equipment. In addition, Vietnam and China southern power grid network, also need to satisfy the operation requirements of China power grid.

EVN is very attention to the technical standard. With the expansion of the power grid and power, opening-up and cooperation, the establishment of technical standards is very urgent for electricity. Hope to be able to close cooperation with China in the field of standardization.

Vietnam's problems at present, China will be able to provide a good solution, but Vietnam aspects of China's specific technology and the ability to understand enough, communication channels are not very clear. So, it is necessary in both sides more to increase communication.

Malaysia

Malaysia grid consists of west Malaysia grid power grid and east Malaysia, east Malaysia and west by the south China sea apart, more than 600 km. In 2002, the installed capacity of 14.024 million kilowatts.

Malaysia's power system by the national electric power company (TENAGANASIONALBERHAD, TNB), sand and waterlogging, the power companies and independent power generation companies. West Malaysia grid by the national electric power company management in Malaysia, and Singapore and Thailand connected to the grid. East Malaysia grid is composed of the sand waterlogging and sabah electric power company, sabah power company owned by the state power company. East Malaysia and west Malaysia grid has not been connected to the Internet.

1. The state power company in Malaysia

Malaysia was established in 1949, the central electricity board, 1965 to the national power authority, in 1990 changed to state power company (TNB). TNB is one of the largest companies, Kuala Lumpur stock exchange capital market value of about 29 billion ringgit ($7.6 billion), the net worth of us $3.1 billion. TNB have power generation, transmission and distribution.

TNB as a big power company, widely involved in the business field, in addition to prop up its power generation, transmission and power supply necessary for the core business of professional technical and engineering institutions, companies, also in the financial, communications, and manufacturing investment, also have independent research and a university. TNB2002 years revenues of $4.046 billion, $298 million net profit, net interest rate of 7.4%. Malaysia the installed capacity of 14.02 million kilowatts, the TNB is 9.1482 million kw, accounted for 65.3%.

(1) the TNB transmission conditions

Is one of the core business of TNB transmission business, from design, engineering, operation and dispatch to the maintenance of the system, overall responsibility for power grid operation of the west Malaysia.

TNB transmission system across the whole peninsular Malaysia (west), combined with all power plants and users, with 132 kv, 275 kv and 500 kv constitute the national grid.

State grid interconnection in the north, the south and Thailand power bureau, through two submarine cables are connected to the power system in Singapore.

(2) the TNB power status

Peninsular Malaysia (west Malaysia) power generation by TNB and independent power suppliers (IPP), independent power suppliers and TNB electricity purchase contracts.

TNB also in Pakistan has installed 235000 kilowatts of independent power generation companies. The subsidiary sabah power company in east Malaysia sabah also USES power purchase contracts for electric power marketing.

TNB power plant is mainly composed of thermal power and hydropower. Coal-fired power plants using conventional steam turbine, power plant using runoff and capacity of hydropower station. In addition to buy power from its own plant and independent power suppliers, TNB also to buy power from Thailand and Singapore to meet peak demand.

(3) the TNB research and development situation

TNB is equipped with a wholly-owned institute, the name (TNBR) for TNB research company, a former national power authority departments, mainly to undertake research and development work of TNB. TNB to TNBR r&d funding, every year for more than year sell electricity, on the basis of per KWH electricity 0.1 ringgit (about 0.0263 cents). Calculated at TNB quantity sold in 2002, research and development funds of about $16.72 million in 2003. TNBR are involved in the research and development power generation, transmission, distribution, environmental protection, etc.

2. Power technology requirements in Malaysia

Malaysia counterparts very focus on the relevant technical problems of power grid dispatching, they are very honest introduced several major blackouts in Malaysia, and put forward a series of technical problems, hope for further communication and discussion with us. These technology problems include: voltage control problem; System dynamic stability (buckling) problem; Overhead line, cable and transformer overload; Power line lightning protection, fault location and line lightning arrester; The transient fault record, etc.

3. Pay attention to and to solve problems

Malaysia is a good country rich in resources, economic development, to the requirement of electric power system safe and stable and reliable power supply is very high. TNB is the national electric power company, is also a shares of the listed company, so for the high demand for electric power operation technology and management technology, the demand is urgent.

Because the total grid capacity is not big, Malaysia and east horse and west separately, with Singapore and Thailand's power contact is not very close, there are a number of problems with power grid stability. Grid stability accident to happen from time to tome, national blackout happened in 1996, power grid solutions listed accidents happened in 1998. So they are very concerned about the problem of stability of power grid and are keen to technical communication with China.

TNB have relatively complete system of power generation, transmission, distribution, maintenance, but many of the techniques and equipment is not able to fully meet the needs of power system operation and management, a lot of work need to use external resources.

TNB large capacity equipment needs to be imported from abroad, the basic needs of high technology to control the electric equipment imports. Because of the blackout accident in recent time, Malaysia is to evaluate the applicability of the western equipment. Malaysia colleague also noted that China's vast power grid running in good condition, so the electricity control equipment in China, especially in high pressure and ultrahigh pressure relay protection equipment is very very attractive to them.

With years efforts made by Bueno Electric technical Team,the Distributed Remote I/O Modules series products were finally worked out and successfully passed the testing made by related authority.We are positive that these series products would bring the impact onto the I/O market.

Bueno Electric I/O modules series are based on 3 protocols: Modbus RTU(ASCII),Modbus TCP and CAN. And the hardware interfaces are RS-485 terminal and Ethernet. The function categories include DI,DO,AI,AO,power relay,TC and RTD.We can cover most functions that the inudstrial projects requires.

With mature technology and high quality components and chips, our I/O modules series will be a black horse in this industry.In the future, we are scheduled to develop out more prorotocls like CANOpen,DeviceNet,BacNet and etc,which would be the great supplement to our product and protocol ranges.

The residents of the western part of Lithuania will now be able to enjoy a more reliable supply of electricity thanks to the reconstructed transformer substation in Klaipėda, which will also ensure more secure transmission of electricity. During the three-year reconstruction, the new equipment and advanced control systems were installed in Klaipėda transformer substation. Now the Klaipėda substation is ready to be connected with NordBalt power interconnection, the construction of which is due to be finished in one year's time.

"The reconstruction of one of the key electricity transmission hubs in Lithuania is another important step towards the successful implementation of the NordBalt project, a power interconnection between Lithuania and Sweden. The substation's reconstruction was carried out to the highest standards of security and reliability of electricity transmission. Now we will be able to ensure a better control and management of the power system and deal with any disruption of the power system in time and more effectively," said Karolis Sankovski, Head of the Strategic Infrastructure Department and Member of the Board of the Lithuanian electricity transmission system operator Litgrid.

In one year the Klaipėda substation will become a vital hub of electricity transmission in Lithuania. The Klaipėda substation which is now used to transmit electricity via high voltage cross border lines with Latvia and Kaliningrad will transmit electricity from Sweden when NordBalt is put into operation. The Klaipėda substation was also connected with the Klaipėda-Telšiai power line, the first 330-kV power transmission line built since the restoration of independence.

The reconstruction of the Klaipėda substation involved the dismantling of old 330-kV and 110-kV sections, the renovation of more than ten of 110-kV overhead power lines and cables, and the construction of new modular buildings for 10-kV, 110-kV and 330-kV switchyard control rooms. The Klaipėda substation has been equipped with two autotransformers, the most powerful in the Lithuanian electricity transmission grid, and new control rooms from which the substation's data is automatically sent to the System Control Center in Vilnius. The place for building the HVDC back-to-back converter station of NordBalt was well thought out, by applying advanced planning strategies and technological solutions: the part of the converter station's building occupies the territory of the old 110-kV switchyard, with the new 110-kV switchyard built nearly.

The reconstruction of the Klaipėda substation started in February 2012, with the estimated cost of EUR 65 million of which nearly a third was financed from the European Regional Development Fund.

The debut of new model of DeviceNet fiber optic converter attracted many customers' eye,including a Norwegian Gas transmission project which uses 50 pieces of converters to embed into the data acquisition system.The new DeviceNet fiber optic converters is invented by BE team who adopts the most advanced technology in the world.The customer wants to transmit DeviceNet data to more than 6km,which can not be achieved by traditional products due to the cascading problem of DeviceNet when it's on long distance.BE solved all these problems and can ensure the converter work in good condition even when it's at high rate and very long distance.
