【摘要】 讨论了采用三相Yd11接线牵引变压器的铁路牵引系统中的负序电流、负序电压和不平衡度的计算方法,实现了对牵引系统潮流分析和负序计算的仿真软件的开发,并给出了几组仿真结果。利用该软件可以对某一特定线路上,在某一种机车运行策略下,牵引系统的负序进行仿真和分析,从而可以为牵引系统的设计提供依据。更多还原

【Abstract】 It discusses the calculation of NPS (Negative Phase Sequence) current, NPS voltage and unbalance rate in rail traction system with three-phase Yd11 connected transformer, implements the software development for traction flow calculation and NPS analysis, and presents several simulation results. This software can be used to simulate and analyze NPS of rail traction system of a fixed line with a certain train running strategy, and therefore is useful for the design of the traction system.更多还原
