±800kV特高压直流工程直流滤波器设计研究

Transformer Substation Monitoring System Based on CAN2.0B

直流滤波器是特高压直流输电工程直流场重要成套设备之一,笔者在总结前期特高压直流输电工程系统研究结论的基础上,研究分析了＋800 kV特高压直流输电工程直流滤波器设计需要考虑的关键问题,包括滤波器形式,直流侧谐振,要考虑的典型故障;介绍了用于计算直流滤波器典型故障的模型和方法。以云广＋800 kV特高压直流输电工程为例,对直流侧谐振进行了校核,对直流滤波器设备暂态定值进行了计算。研究结果表明,云广±800 kV特高压直流输电工程直流滤波器设计是合理的,可满足直流系统安全可靠运行要求。

The data communication based on the user layer protocol Qucan_A between transformer substation and the field sys tem has been accomplished,which the monitoring picture is developed by Kingview.The master driver program is designed by vb which provides the interface between Kingview and the driver programe.KingView Exchange information with VB by means of OPC interface,thus the monitoring system has been realized which have the functions of measuring,sampling, communication,control and running management,Order of events recorded,offgauge alarm,and etc.the system runs well in practice,Consequently,it further verifies the advancement and practicability of the transformer substation network.
