赵山渡水电站计算机监控系统

Computer Supervisory Control System of Zhaoshandu Hydropower Station

赵山渡水电站采用以计算机监控为主、简化常规控制为辅的监控方式． 电站的计算机监控系统是采用 PSC－2100H 型开放分布式计算机监控系统，其主要监控对象有：2 台水轮发电机组，机组出口 6.3 kV 配电装置，全厂的油、气、水系统，2 孔进水口检修闸门和尾水事故检修门，16 孔泄洪道弧形闸门，35 kV 升压站的主变压器、线路及配电装置． 文中主要介绍了计算机监控系统的结构、配置及系统的功能，并对监控系统的实时性、可靠性和运行安全性作了论述．

A computer supervisory control system is adopted and at the same time the simplified conventional control measures are used as stand-by in the Zhaoshandu Hydropower Station． The PSC-2100H distributed open computer supervisory control system is used for the station． The main equipment monitored includes ： （1） two hydrogenerator units； （2） 6．3 kV distribution system in the output unit； （3） the oil， air and water supply systems of the hydropower plant； （4） two intake gates and tail emergency gates； （5） sixteen spillway radial gates； and （6） the main transformer， electric line and distribution equipment． This paper presents structure， configuration and function of the computer supervisory control system． The monitoring real-time performance， reliability and safety of the system are also discussed．
