智能变电站事故总信号实现方法分析

Research on the Realization Method of Integrated Accident Signal in Intelligent Station

变电站事故总信号反映事故跳闸信息,是设备运维人员需要重点关注的信号。常规变电站事故总信号由操作箱内的二次回路实现,各厂家的设计方案一致。智能变电站事故总信号则由智能终端内的回路或逻辑实现,不同智能终端事故总信号实现方法也不尽相同,且与遥控功能联系紧密。本文结合遥控功能,分析了智能变电站3类事故总信号的实现方案,总结了各自的优缺点和调试方法,为继电保护设备调试或检验提供参考。

The integrated accident signal reflects the accident trip.It is very important to the equipment operation and maintenance personnel.The integrated accident signal of the conventional substation is realized by the secondary circuit in the operation box.The design schemes of all manufacturers are consistent.In smart substation,it is realized by the circuit and logic in the intelligent terminal.The methods for debugging the different equipment also vary.The accident signal is closely related to the remote-control function.This paper analyzes the method of three kinds of integrated accident signal,summarizes their advantages and disadvantages,and provides a method for the relay protection personnel to debug the equipment in combination with the remote control.
