分布式电网故障信息集成与智能分析的研究及应用

Research and Application of the Fault Information Integration and Intelligent Analysis in Distributed Grid

研发了一套电网故障信息智能综合处理分析系统,将采集到的分布式二次设备信息通过智能分析系统诊断处理、整合,建立了省地调一体化的电网故障信息智能综合处理平台。其主要实现方式分为两步,具体包括在厂站端将保护装置接入信息子站,将故障录波器接入录波代理装置,分别给信息子站及录波代理装置配置高速通信网通道,和调度端的主站系统互联;在调度端主站采用分层分布式的软件设计框架,其中在数据层设置保护通信服务器及录波接入通信服务器,分别接入保护及录波器信息,在应用层对信息进行处理,利用故障序号判断、经验时间判断等智能处理手段,实现两种信息的有效整合和处理。该系统的实现提升了台州电网继电保护专业的运行管理水平,在台州电网近年来调度运行、灾害处理中发挥了较大的作用。

This paper presents a grid fault information intelligent analysis and processing system. It is a platform of fault information intelligent processing, used for an incorporate control center system of province and district level. It works in two parts, substation and control center. In the substation, a slave system device gather the information of relays and deliver it to the master system in the control center through Ethernet, and a recorder proxy device galher the information of recorders and deliver it to the master system through another Ethernet channel. The software in the control center has a layered and distributed structure, and import the information of relays and recorders with two iso- lated server in the data layer. The application layer of the software system can gather the information to a integrated report of a grid disturbance or fault with special process, include of using the fault index ,fault time, etc. This system has been used in the control center of Taizhou district in Zhejiang province, and remarkably improves the level of management.
