电力系统故障区域录波自动分析关键技术

提出一种电力系统故障区域录波自动分析方法并进行系统研制，该系统是基于广域信息的继电保护实时评价系统的重要组成部分。电力系统故障区域录波自动分析系统可自动生成事故综述，具有录波的时序分析、动作行为判断、定值灵敏度分析、模拟量分析、外回路分析、采样回路分析、定值分析、压板分析等功能，并对波形中的异常情况进行告警。通过自动分析系统的使用，提高了电力系统故障录波分析的效率和质量，大幅度减少了人力成本和事故分析的时间，增加了事故分析的广度，提高了事故分析的质量。该系统已在某电力公司调度中心试运行，运行结果表明该方案具有良好的可行性。

Key Technology of Automatic Analysis of Fault Area Wave Recording of Power System

In this paper, an automatic analysis method of power system fault recording is proposed and developed. It is an important part of relay protection real-time evaluation system based on wide area information. Through the use of automatic analysis system, the efficiency and quality of power system fault recording analysis are greatly improved, and the labor cost is greatly reduced, which greatly reduces the time of fault analysis and improves the quality of fault analysis. The system has been trial run in a power dispatching center. The operation results show that the scheme has good feasibility and effectively improves the maintenance efficiency of operation and maintenance personnel.
