Practice of Improving the Stability of Switching Signal Transmission in Computer Monitoring System
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.
