Abstract In the power supply system of high speed railway, the generated harmonics can not only influence the electric energy quality of power system, occur the voltage fluctuation and flicker, and affect the service life of traction equipment and traction transformer of electric power substation, but also cause the secondary protection misoperation of automatic control system, and affect the normal operation of the train. With the increase of overhead contact line transmission, the generated harmonics increased the communication interference. Therefore, on the basis of analyzing the generation and spectrum of harmonics in power system, an improved S transform method is introduced in order to propose a harmonic measurement and analysis method based on improved S transform for power supply system of high speed railway in this paper. The proposed method can effectively realize the harmonic measurement and analysis of power supply system. In order to testify the effectiveness of the proposed harmonic measurement and analysis method, Yingkou substation of Harbin-Dalian high speed railway is selected in here. The actual analysis calculation and experiment results show that the proposed method can effectively measure and analyze the harmonic in the power supply system of high speed railway. It provides a theoretical basis for solving the practical engineering problem of power supply.
