    Abstract This paper uses two systems with simple configuration as an example to calculate the impedance of the 3 rd，5 th and 7 th harmonics and their voltages for the user IPC（internal points of coupling）， gives the simplified method of calculating the impedance of zero-sequence，positive-sequence and negative-sequence harmonics as well as harmonic voltage，and analyzes its practical significance for engineering design.
