摘要
本文以联合研制成功的水电站可编程控制调速器为对象，详细介绍其硬件与软件构成及工作原理。同时，对多种调节模式等方面也进行了一些探索。
Based on the speed regulstor of the programmable controller,which is developed for the hydropower station by our joint efforts,this paper introduces the compositions of its soft and hardwares and its working principle.A number of regulation modes are also explored in some way.
