IIn this paper,two simulation models of power factor measurement are proposed,and verified in sine RC circuit.Simulation results show that the values measured by the two models are in conformity with the theoretical ones.Then these two measurements models are connected with a three-phase high power supply circuit for a further simulation.Also,the obtained power factor is consistent with the experiment result,which further validates the reliability of the two simulation models of power factor measurement.
