| Abstract: | This essay introduces the application of P-Q instantaneous reactive power theory in harmonic current detection of active power filter.It chooses the power to be compensated and compares the compensated waveform with uncompensated waveform of an electrified wire fence.At same time,this article utilizes the Matlab to simulate the model proposed.Theory and simulation both validates the effectiveness of the proposed method.This theory can be applied in the harmonic current detection of active power filter perfectly. |
