摘要
在水轮机调速器系统中残压测频是主要环节,其测频的稳定性和精度直接反映调速器能否快速响应,并稳定运行。高次谐波的引入是造成调速器残压测频不稳定的主要原因,因此需要设计一个新的残压测频电路,彻底消除高次谐波的影响。
Frequency measurement of residual voltage is one of main procedures for speed governor of hydro turbine, the stability and sion of which directly reflect whether speed governor can response fast and be in operation stably or not. Introduce of high order harmonic main reason resulting in the instability of frequency measurement of remnant voltage for speed governor, so it needs to design a new type cult to eliminate the influence of high order harmonic absolutely.
