英文摘要：
Considering the dynamic fluctuation of the harmonic distortions caused by the topology variations of the traction power supply system（TPSS）as a result of the running high-speed trains,in order to evaluate the harmonic distortion levels of such traction system,a novel TPSS evaluation method adopting train timetable was presented here,based on the traction calculation and the calculation of traction power for a running train during the whole operating process.Firstly,combining the timetable and traction calculation of the running trains,the traction loads performance during a day was obtained.Then,the dynamic simulated model of TPSS was established.The results of both fundamental and harmonic load flow methods showed the real-time harmonic performance of each key location in the system.Finally,the maximum value,99% and 95% probability statistics of the results were used to evaluate the harmonic indices of the TPSS.The comparisons between simulation results and field tests verified the effectiveness of the proposed method.The proposed method can be further used for the design and optimization of the TPSS and train timetable.
