Abstract

Frequency and phasor are the most important quantities in power system operation. Frequency reflects the dynamic energy balance between load and generating power. To estimate of power system frequency, an accurate digital tracking algorithm by using phasor angle difference is presented. For an evaluation of the proposed technique, simulations by EMTP have been performed. Test results were showed the algorithm's accuracy under the effect of noise and changes in frequency and amplitude on the input signal.
