| Abstract: | An introduction was made on the characteristics of two kinds of unit frequency measuring methods, i.e. toothed disk and residual voltage frequency measuring which are adopted for the governor of Pubugou Hydropower Station. The original toothed disk frequency measuring circuit rendered inaccurate value with considerable fluctuation. The author presented the upgrade method of toothed disk frequency measuring hardware circuit as well as the effects. |
