| Abstract: | Frequency is taken as the important parameter which could reflect the power qualities. The exact measure of frequency is one of the most important evidence which could scale the healthy running of the power system. Furthermore it is the first problem of other power-system parameters that must be resolved. This article bringed forward a few digital measures and gave the emulation. And making the comparison on precision, using areas and merits and shortcomings. |
