为提高汽油发电机组调速性能,本文利用稳态特性平衡图对汽油机、调速器和传动机构的匹配进行了分析,并在对调速系统动态特性分析的基础上采用机械电子调速器,它的特点是将受机组频率变化及其微分量所控制的电磁执行器迭加在机械调速器上,以进一步降低稳定调速率和转速波动率,抑制瞬时调速率和稳定时间,使瞬时调速率在全负荷突加时达到2.5%、突减时达到2.4%左右,稳定时间缩短为1～1.6秒。这种装置结构简单,性能良好,机电可以串联使用,不需要阻尼器。本文介绍作者在提高BSF-12型双频供电机组调速性能方面所做的工作,这种调速器可应用到其他类型机械调速器上。
In order to improve the governor performance of gasoline generator sets, this paper analyzes the matching of gasoline engine, governor and transmission mechanism by using the steady-state characteristic balance diagram. Based on the analysis of dynamic characteristics of governor system, Its characteristic is superimposed on the mechanical governor by the electromagnetic actuator controlled by the variation of the frequency of the generating set and its derivative components so as to further reduce the rate of steady speed regulation and speed fluctuation and the instantaneous regulation rate and the stabilization time, Instantaneous transfer rate reached 2.5% at full load sudden increase, abruptly reached about 2.4%, the stabilization time was shortened to 1 to 1.6 seconds. This device has a simple structure, good performance, electromechanical can be used in series, does not require a damper. This article describes the work done by the author in improving the speed regulation performance of the BSF-12 dual-frequency power unit, which can be applied to other types of mechanical governors.
