一种串并联混合型铁路贯通电源技术研究
Research on a Series-Parallel Hybrid Railway Through Power Supply Technology
摘要
Abstract
Abrstact:In order to ensure the reliability of through power supply lines for railways in areas with power shortages,this paper proposes a railway through power supply technology based on a series-parallel hybrid active voltage quality regulator.This technology enables ideal railway through power supply through direct power draw from the overhead contact system(OCS)and conversion along with series compensation.Building on an analysis on the topology of a series-parallel hybrid active voltage quality regulator,the design allocates parameters for its key components.The design also incorporates a repetitive control algorithm for the parallel converter and a dual closed-loop control strategy—encompassing both voltage and current—for the series converter,to accommodate the different control objectives of the series and parallel sections.The feasibility of the proposed series-parallel hybrid railway through power supply technology was verified through applications in typical engineering scenarios.The engineering application results show that the output voltage deviation of the railway through power supply does not exceed 6.7%,the three-phase voltage imbalance does not exceed 3.4%,and the harmonic voltage distortion rate does not exceed 3.9%.All power quality indicators of the railway through power supply utilizing the proposed technology meet the allowable limits specified in Chinese national standards.关键词
