Design And Application Technology Based On Substation Monitoring And Control System Of Ethernet

This paper mainly studies are the design and application of technology based on Ethernet substation system. Substation is an important link in transmission system and major monitory point in the grid. In recent years, in order to improve the quality of power supply, ensure the safety of the electricity system, reliable, economic operation, substation automation system is springing up development.Firstly LAN technology as a representative of Ethernet is introduced in this paper, and this technique applied in substation automation system has incomparable advantage. Due to the special environment of transformer substation data communication is required rapidly real-time response ability, reliability of stability and fine electromagnetism compatibility. Because the communication network is required to meet different types and characteristics of information transmission requirements, adopting unified TCP/IP protocol can avoid the different communication protocol and can directly connnect network computer networking without additional hardware devices. Secondly, the Industrial Ethernet in Substation Substation Spark model and monitoring system are analysed. Substation system can not only improve the efficiency, reliability and maintenance of substation operation, also raise grid operation management level and the quality of power supply, reduce personal operating. Finally, substations monitoring system is built by realinfo configuration software. Substation monitoring system established achieves the status of substation equipment and line a real-time running surveillance, alarming and other functions. It has great practical value.
