Research on Retrofit and Optimization of Timing System of Thermal Power Plant Units
火电厂机组授时系统的改造优化研究

摘要

电力系统的运行状况瞬息万变，这就对火电厂机组设备安全稳定运行提出更高的要求，自动控制系统要准确反映、判断、控制电力系统的运行，必须要有一个统一的时间基准。同时事故追忆（SOE）系统更要及时处理、分析事故原因。本文介绍火电厂授时原理，对时方式，论述DCS系统国产化改造中授时系统优化改造工程情况，分析目授时系统系统存在的问题，提出解决方案。

Abstract

The operation status of the power system is changing rapidly, which puts forward higher requirements for the safe and stable operation of thermal power plant equipment. To accurately reflect, judge and control the operation of the power system, the automatic control system must have a unified time benchmark. At the same time, the accident recall (SOE) system needs to deal with and analyze the cause of the accident in a timely manner. This paper introduces the timing principle and timing method of thermal power plants, discusses the optimization and reconstruction project of timing system in the localization of DCS system, analyzes the problems existing in the visual timing system, and proposes solutions.
