| Abstract: | Having analyzed, the definition of reactive power in time domain and frequency domain,this paper put forward a method of measuring the reactive power of three-phase asynchronous motor based on Hilbert transform. Newton two-order interpolation is also used to synchronize the voltage and current. This method meets the demand of the test system which considers harmonic. |
