Abstract
Considering that the existing measurement method of reactive power is complex in calculations and difficult to realize,a measurement method of reactive power based on instantaneous reactive power theory is proposed in this paper.After the instantaneous voltage and current shift their phases simultaneously,the reactive power is obtained by using simple calculations and low pass filter,so there is no coordinate transformation or trigonometric function calculations.The proposed method is simple and easy to implement,with which the measured values can provide the basis for real-time reactive power compensation under both sinusoidal and non-sinusoidal circuit conditions.Simulation results indicate that the proposed method is feasible and accurate.关键词
