Proposes an instantaneous reactive power ip-iqharmonic current detection method which has been improved on the basis of the resonant controller. It can greatly improve the accuracy and real-time performance of detection. It is popularized and applied to detect harmonic current of active power filter. When the load changes suddenly, the method can ensure a fast transient response, realizing zero error of steady state and improving the execution speed of detection algorithm. After compensation, the current distortion rate of the grid becomes low, and the dynamic tracking performance of APF better.
