摘要
水电站计算机监控系统用于实现厂内各系统运行监视、状态控制、数据采集、数据处理、事件记录等功能,是电站极为重要的系统之一,同时计算机监控系统负责将各采集信息及控制功能上送至集控中心、电网调度,以实现远程监视及控制.随着"无人值班、少人值守"运行理念的推广实施,计算机监控系统上送信号的稳定变得尤为重要.通过对电站一次开关量信号误报及漏送事件进行分析,解决了站内计算机监控系统的固有漏洞,总结了提高开关量稳定性的方法.
Abstract
The computer monitoring system for hydropower stations is used to achieve functions such as monitoring the operation,status control,data acquisition,data processing,and event recording of various systems in the plant.It is one of the extremely important systems in power stations.At the same time,the computer monitoring system is responsible for transmitting various collected information and control functions to the central control center and power grid dispatch to achieve remote monitoring and control.With the promotion and implementation of the operation concept of"unmanned and few people on duty",the stability of signal transmission on computer monitoring systems has become particularly important.By analyzing the false alarm and missed transmission of a switch signal in a power station,this paper solves the inherent vulnerabilities of the computer monitoring system in the station and summarizes methods to improve the stability of the switch signal.
