基于EMS一体化的保护定值远方操作研究与应用

为了提高传统定值现场修改的效率,提出一种基于EMS一体化的保护定值远方修改系统。利用IEC104通信规约的特点并进行扩展,结合扬州电网调度自动化OPEN-3000系统,研究并提出远方操作系统的整体架构和软件平台设计,最后将该系统应用于扬州220 kV广陵变进行了现场测试。运行结果表明,该系统可以实现远方修改保护定值、切换定值区和在线投退软压板等功能,提高了调度管理及运行管理水平。

Research and application on relay protection setting value remote operation based on EMS integration

To improve the efficiency of traditional relay protection setting value local modification, a setting value modified system based on EMS integration is presented. Based on the analysis of IEC104 expanding protocol, and on the basis of Yangzhou power dispatch automation OPEN-3000 system, the whole frame and software design of remote operation system are researched and proposed. To test the performance, the system is applied in Yangzhou 220 kV Guangling substation. The results show that the system can realize the setting value remote modification, the setting value zone remote switch and the soft plate control on-line, which improves the levels of dispatch management and operation management.
