With the high penetration of renewable energy and electronic equipment, the problem of wideband oscillation in power systems is becoming increasingly prominent, which has become a key factor restricting the efficient consumption of renewable energy. A wideband phasor measurement method is proposed and the corresponding device is developed to satisfy the requirements of wideband oscillation mitigation and protection in power systems with renewable energy. Based on the windowed discrete Fourier transform and three peak interpolation, this device can measure multi –mode wideband phasor of multiple voltages and currents. Besides, the amplitude and phase of high frequency phasor are compensated based on the linear regression, which effectively improves the measurement accuracy of the device while ensuring the dynamic response speed. Finally, the measurement performance of the developed device was verified by experimental testing with testers and realtime digital simulation, and the device can provide support for ensuring the safety and stability of power systems and the consumption of renewable energy.
