摘要

本文对江西赣能萍乡发电厂因冰冻雪灾天气引起的小网运行造成的#4机跳机事故进行了详细分析

接着介绍了针对这种电网事故

对现有DEH功能采用放开一次调频、OPC103%保护方案修改等相结合的方法进行补充和完善

最后提出这种小网运行技术改造还需经受真实工况的严峻考验。

Abstract

This paper detailed analysis the accident of Pinxiang Power Plant in which NO.4 Unit was shut down caused by frozen and snow disaster. Then the ways that first frequency modulation with DEH function and OPC 103% protection scheme modification were provided aiming at such isolated power network accident. This technical transformation of isolated power network should be tested by real working condition.
