摘要
针对220 kV高岐变电站远动系统运行存在的问题,阐述了远动系统改造工程的实施步骤,分析其技术重点并提出解决措施。尝试对IEC 60870-5-104远动规约进行扩展,使子站端保护软报文信息直接经扩展规约打包上传至调度主站,实现了保护信息的远方共享。
Considering the problems of the remote automation system of the 220kV Gaoqi substation,this paper expounds the implementation steps of the reconstraction engineering,analyzes the technical focus,then proposes the countmeasures.It tries to improve the IEC 60870-5-104 transmission protocol for directly transmitting relay fault information of the sub-station to the master station of electrical dispatching system,then the relay fault information are shared between the sub-station and the master station.
