Abstract
Aiming at the existing problem in harmonics measurement of power system,the paper presented a collecting method based on frequency multiplication phase-locked. Using phase-locked loop to track power wave,this method not only resolved the impact of spectrum leakage on precision of harmonics(measurement),but also realized quick,accurate and real-time measurement.
