摘要

辅助系统运行可靠性将直接影响水电厂的安全经济运行

因而有必要对辅助系统的运行状态进行实时在线监测。在介绍水电厂高压气系统工作原理基础上

总结了水电厂高压气机异常启、停与相应故障对应关系

提出了高压气系统关联监测模型

并利用梯级水电厂群远程集控系统提供的海量数据源

建立了水电厂高压气系统的远程分析与故障诊断平台

目前

该平台已投入工程试运行

成功诊断出水电厂高压气系统漏气故障。

Abstract

The reliability of the auxiliary system will directly affect the safe and economic operation of hydropower plant

so it is necessary to on-site monitor and analyze the running state of auxiliary system for hydropower plant.On base of the instruction on the structure and working principle of the high-pressure gas system

the relationship between the abnormal actuating/showdown state of high compressors and corresponding failures of high-pressure gas system is summed up

and the relevance monitoring model for high-pressure gas system of hydropower plant is put forward.Then

by making use of the massive data sources provided by the cascade hydropower plants group remote centralized control system

the high-pressure gas system remote analysis and fault diagnosis platform has been established.At present

the platform has been put into trial industrial application

and two gas leakage failures of high-pressure gas system in a certain hydropower plant have been detected successfully.
