With the continuous development of high-speed railway construction, traction power supply technology has also been rapidly developed. Due to the nonlinearity and high power of the traction load, the power consumed by the high-speed EMU may adversely affect the voltage and current of the regional power grid during the operation of the high-speed railway. In this paper, the positive sequence, negative sequence and zero sequence components and spectrum of high speed EMU under different operating conditions are analyzed according to the measured data of traction power supply institute. According to the actual data, the root mean square value, imbalance degree and harmonic distortion rate are analyzed and calculated. The graph is drawn by MATLAB, and the relevant literature is consulted and combined with the relevant data obtained by drawing the graph and calculating to analyze the imbalance degree and harmonic to evaluate the power quality.
