This paper presents a compensation method of current harmonics and reactive power under three-phase four-wire system. The definition of generalized instantaneous current in αβο coordinate system is given. The instantaneous reactive power is analyzed under the three-phase four-wire system The simulation results of this circuit show that the compensation method can effectively eliminate the current harmonics and reactive power.
