【Abstract】 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.更多还原
