摘要
在分析水轮发电机测频现状的基础上,讨论了基于高速计数模块(VHSC)的新型测频环节,并与常规测频环节进行了比较,得出新型测领环节较前者优越的结论。
Based on the analysis of present situation of frequency measurement of the hydro-generating set, a new type of frequency measurement link, which is based on the high-speed counting module, is discussed. And its comparision with the conventional frequency measurement link is made. The conclusion is that the new type of frequency measurement link is finer than the conventional one.
