摘　　要：电气化铁路电能质量问题集中体现在负序、谐波、无功及电压偏差等方面,机车类型、线路条件和运行组织等因素直接影响了电能质量状况。在电气化铁路牵引供电系统综合测试的基础上,掌握了普速客货混跑线路、重载线路以及高速线路牵引负荷特性,定量评估了其对外部电力系统电能质量的影响,探讨了其共性和特殊性,并分析了主要原因。针对一种新型电能质量控制方案,建立了主电路和牵引负荷模型,仿真验证了其可行性和技术优越性。The problems of power quality of electrified railway are embodied in the aspects of negative sequence, harmonics, reactive power and voltage deviation. The factors such as the type of locomotive, line condition and operation organization influence the power quality directly. In this paper, the load characteristics of the line of mixed freight and passenger, heavy haul and high speed railway are obtained based on the field testing of traction power supply system. The quantitative assessment of power quality of the exterior power supply is given, the generality and particularity are discussed and the main cause is analyzed. The research on a new power quality control scheme is carried out, the models of main circuit and traction load are built, and the feasibility and superior technology of the scheme are proved by the simulation.
