一、P-100型调速器摆动的原因分析调速器的摆动,可能是由永磁机、主机及引水系统等外界因素引起的,也可能是由于调速器本身的参数调整不当或制造工艺上(如干摩擦等)以及安装调整上的缺陷引起的,另外,水电站水工、电气等方面的缺陷,也会造成调速器的摆动,总之,造成调速器摆动的原因是多方面的,必须具体分析。玉渊潭水电站P-100型调速器也曾发生过摆动现象。其特点是在带负荷运行时,主配压阀和接力器产生周期性摆动,每秒摆动达三次之多(见图1),并与主机转速(187.5转/分)相对应;
First, the P-100-type governor swing analysis Governor swing, may be caused by the permanent magnet machine, the host and the diversion system and other external factors, may also be due to the governor itself, the parameters of improper adjustment or manufacturing Process (such as dry friction, etc.) as well as installation and adjustment of the defects caused by the addition, the hydropower station hydraulic, electrical and other defects, will also cause the governor swing, in short, resulting in governor swing is due to many aspects It must be specifically analyzed. Yuyuantan Hydropower Station P-100 Governor also had a swing phenomenon. It is characterized by the load with the main pressure regulating valve and relay produce a periodic swing, swinging up to three times per second (see Figure 1), and the host speed (187.5 r / min) corresponds;
