Broadband Measurement and Resonant Detection Technology of Power System Based on new Sensor

With the new energy generation gradually becoming the main power supply, the power system presents broadband characteristics, the difficulty of energy measurement is increased, and the accuracy of harmonic detection is decreased. This paper proposes a broadband measurement and resonance detection technology for a power system based on a new type of sensor. Firstly, the broadband measurement algorithm of the electronic watt-hour meter is designed, and the measurement data can be obtained directly according to the extracted information to improve the accuracy and reliability of measurement. Secondly, the causes of harmonic harmonics in the new power system are analyzed. The real-time amplitude and frequency are detected by the Hilbert transform algorithm, and the harmonic distortion rate and amplitude oscillation are used to judge the resonant frequency. Finally, the effectiveness of the proposed method is verified by simulation based on measured sensor data.
