500kV变电站保护设备远方遥控应用

The Application of Remote Controlling Protective Equipment in 500 kV Substations

实现保护设备远方遥控,对实现500 kV变电站无人值班、集中监控的运行管理模式,确保无人值班变电站安全、可靠、可控、可知的良好性能和较高自动化水平具有重大意义。以国家电网公司第一座批照无人值班设计的500kV变电站木渎变保护设备远方遥控为例,介绍了保护设备远方遥控的实现方法、控制对象和软硬压板使用逻辑,并结合近一年的使用情况提出了改进措施。

The remote control of protective equipment is of great significance to the unattended and centralized monitoring operation and management of 500 kV substations, which is also benefit for the safety, reliability, controllability, recognizability and high automation of unattended substations. As one of the unattended 500kv substations in the State Grid ,500kV Mudu substation realized remote control of protective equipment. This paper introduces the ways of remote controlling, controlling object and the logical relationship of software and hardware, and also presents some improvement measures based on one year＇ s application.
