可编程序控制器在水电厂机组自动控制中的应用

Application of programmable controller in the automatic control or hydropower generating unit

着重介绍应用于水电厂的可编程机组ＲＴＵ控制单元的结构配置、基本工作原理以及整个控制软件的设计，给出了比较有特殊性的几个子程序的编程方法。该控制单元投运后的安全可靠得到了用户的肯定和欢迎。

This paper describes the structural delay, basic functional principles and the whole control software design of programmable control element for generating unit which could be applied to hydropower station, and gives the programming method for several comparatively special sub-programs. The safety and reliability of the control element have been affirmed by users when it has been put into use.
