适应智能电网继电保护定值的在线管控方案

针对智能电网建设中无人值守变电站运行模式下继电保护设备整定值管理存在的弊端,分析了传统整定值运维方式的不足,并基于继电保护整定值计算系统和继电保护远程修改定值功能,提出了一种继电保护整定值在线管控的方案。通过定义基于CIM-E格式的定值单文件及数据模糊识别规则,解决了不同系统间数据共享的问题,通过建立继电保护整定值管理系统,实现了在调度端对继电保护设备整定值的计算、远程调取、在线下装以及自动校核全面管控等功能。所提出的定值在线管控流程已经成功试点应用,其可靠性获得了有效验证,提高了继电保护管理和运维人员的自动化水平。

On-line Management and Control Scheme for Relay Protection Settings of Smart Grid

To overcome the shortcomings of relay protection settings management in unattended substations, based on an analysis of the traditional management mode and the remote modification settings function of relay protection, a scheme for online management and control of protection settings is presented. By defining the storage format of protection settings data based on CIM-E and drafting regulations for data fuzzy recognition, the scheme has solved the problem of data sharing between different systems. The protection settings management system based on the scheme has realized function of on-line download and remote access to relay protection settings in the power grid dispatching center. Successful application of the system has remarkably improved the automation level of relay protection operation and maintenance.
