文摘A digital measuring method for power system harmonic impedances is presented.Based on the idea of injecting current to the power system and measuring harmonic impedances directly,a digital receiving set is designed to receive harmonic signals from the power system.To obtain the harmonic impedances,the signals are handled by digital filters.Simulation results show that this measuring set fits the requirement of industrial measurement.
