The Importance of Monitoring of Smart Meters   In the more than 100 years history of the electric power industry, "smart meters" is still in the early stages of deployment and use. Because of the electric meter is the front end of the electric power company "register", must be very accurate.Although there are a large number of requirements for the meters, performance specifications and regulations, and electric power company is trying to ensure the accuracy of meter, but in fact,…

In industrial control, some input (such as pressure, temperature, flow rate, rotational speed, etc.) is a continuous change of analog, some actuators (e.g., servo motor, regulating valve, recorder, etc.) for PLC output analog signal, and the PLC CPU can only deal with digital quantity. Analog was first sensor and transmitter is converted into A standard current or voltage, such as 4 ~ 20 ma, 1 ~ 5 v, 0 ~ 10 v, PLC with A/D converter convert them to digital…

Power substation monitoring and control system can provide real-time information, especially the switch and protection behavior of information (accident alarm information), and make the personnel on duty and system dispatch personnel to grasp the initiative of security control, accident treatment, at the same time can improve the management level of power network, reducing the loss of substation, power distribution, improve the quality of power supply. A specific monitoring, system objects:Main microcomputer monitoring system of transformer substation monitoring object has the…

Bueno Electric's GPS Sync Clock 1. Overview Grid dispatching integrated automation system of SCADA function for the dispatcher, set each substation controller provides real-time data and information, and can make them easy to repeat or accident history data and information query. In system design, the need to consider more is network structure, communication protocol conversion, data storage medium and satisfy the requirement of the SCADA function several performance indexes, without taking into account the system so what is the impact…

The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. PTP was originally defined in the IEEE 1588-2002 standard, officially entitled "Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems" and published in 2002. In 2008, IEEE 1588-2008 was released as a revised standard; also known as PTP Version…
