摘要
国家电网公司新的运行模式要求调控中心监控人员对变电站设备开展远程遥控。现有调度技术支持系统采用的IEC 60870-5-104规约在遥控命令传输和校验过程只校验点号信息,存在因点号对应关系错误导致误遥控的可能性。通过扩展IEC 60870-5-104规约,实现设备编号和点号的双重校验,以及测控装置IP校验,可以大幅降低因主站和变电站综自系统监控信息表点号不对应带来误遥控的可能性。
The new operation mode in the State Grid requires the operator to control substation equipment remotely. In the current dispatching support system, the IEC 60870-5-104 protocol only checks control point number during remote control command transmission and verification process. This may result in mal-operation of remote control because wrong corresponding relation between control point number and device. By extending the IEC 60870-5-104 protocol, double check among device ID, control point number, and device IP is achieved. It greatly reduce the possibility of mal-operation of remote control caused by wrong corresponding relation between control point number and device.
