摘要

广州发电厂Ｃ５０机组投产后，经甩负荷试验，发现调速系统动态特性不合格。通过对调速系　统油动机的改进，减小了调速系统迟缓率，加快了油动机的关闭速度，从而解决了调速系统　动态特性超调量过大的问题。

Abstract

After putting C50 type unit into operation at Guangzhou Power Plant

it was foun d that the dynamic characteristic of its speed-governing system isn′t up to standard via full load rejection experiment. Through retrofitting the servomotor in said governing system

the actuation slowness of the speed governing system has been improved

enhancing the closing velocity of the servomotor

and then the problem regarding the excesive overshoot of the dynamic characteristic for the speed-governing system having been resolved.
