中文摘要：
为应对电气化铁道供电系统电能质量问题,提出了一种能适用于平衡牵引变压器的混合型电气化铁道电能质量综合治理系统（H-RPQIS）。分析了该系统有源部分的端口电压特性,给出了LC耦合支路的参数设计方法,并将其与传统铁路功率调节器（RPC）进行了容量对比分析。分析结果指出在同等补偿电流下H-RPQIS有源部分的补偿容量大幅低于RPC系统。结合某40 MV·A牵引变电所的实测数据对系统进行了仿真研究,结果显示H-RPQIS有源部分的补偿容量约为RPC的20%~30%,验证了H-RPQIS的补偿效果及容量分析的正确性。
英文摘要：
An H-RPQIS（Hybrid Railway Power Quality Improvement System） is proposed to comprehensively improve the power quality of traction substations with balance transformers. The port voltage performance of its active part is analyzed,the parameter design of its LC-coupling branches are given,and its power capacity is compared with that of traditional RPC（Railway static Power Conditioner）. Analytical result indicates the compensation capacity of its active part is much smaller than that of RPC system. Simulation is carried out for a real 40 MV ＂A traction substation based on the test data and results show that,the compensation capacity of its active part is about 20 %-30 % of that of RPC,verifying the compensation effect of H-RPQIS and the correctness of capacity analysis.
