Probability Analysis of Negative Phase-Sequence Current for High-Speed Railway Traction Substation Based on Measured Data

摘要

摘要:为了研究高速铁路牵引供电系统三相电流不平衡问题, 通过分析高速铁路牵引供电系统负荷及V/v接线牵引变压器负序电流,基于概率理论建立了牵引变电所负序电流的概率分析模型.用该模型对京沪高铁某牵引变电所的负序电流进行了仿真分析和实测数据验证,结果表明,利用该牵引变电所的设计参数仿真得到的负序电流概率分布与利用实测数据的分析结果一致,该牵引变电所负序电流概率分析模型能够真实地模拟高速铁路牵引变电所的负序电流分布情况.

Abstract:In order to study the problem of current unbalance in the traction power supply system of high-speed railway, the stochastic process of loads in traction substations and the negative-phase sequence current feature of V/v connection transformers are analyzed, and a negative phase-sequence current probability model was proposed by probability theory. Using this model, the negative-sequence current of a traction substation on the Beijing-Shanghai high-speed railway was simulated and verified with the measured data. The results show that the probability distribution of the negative-sequence current obtained using the design parameters of the traction substation is consistent with the analysis results from the actual data. This proves that the proposed model can reflect accurately the negative sequence current distribution of high speed railway.
