水电站的监控自动化对合理利用水资源、提高发电效益及电站的安全运行有着十分重要的意义。现地控制单元为水电站计算机监控系统的一个重要组成部分,是水电站计算机监控系统的基础,是机组能否安全运行的关键。本文阐述了水电站机组现地控制单元的发展,分析了系统方案的选择,简要介绍了现地控制单元的功能要求及其系统设计。
The automation of monitoring and controlling of hydropower stations is of great significance to the rational utilization of water resources, the improvement of power generation efficiency and the safe operation of power plants. The local control unit is an important part of the computer monitoring system of the hydropower station and the basis of the computer monitoring system of the hydropower station. It is the key to whether the unit can operate safely. This article elaborates the development of the on-site control unit of hydropower station, analyzes the choice of system plan, and briefly introduces the functional requirements and system design of the local control unit.
