| Abstract: | Two simple and practical algorithms are put forward to improve real-time performance of power system frequency measurement responding to the situation of certain frequency trends and the situation of unknown frequency trends. Mathematical reasoning and simulation results show that the proposed algorithms can track the power frequency in real time, require less length of digital filter window, they are simple and easy to implement, and have good real-time character. |

| Keywords: | power system frequency calculation real-time measurement low pass filter |
