| Abstract: | A new method for measuring power system frequency is presented in this paper. The
calculation of the method is simple and fast. The accuracy of measurement is raised highly
by adaptive sampling. The simulation test show that the method can measure the frequen-
ey correctly when change of frequency is less than 50Hz and the measurement error is less
than 0.0005Hz. |
