摘　　要：针对高速铁路全电缆电力贯通线运行过程中容易出现末端电压升高、功率因数低等问题,本文结合高速铁路全电缆贯通线路的运行特点,原理性分析了影响贯通线电能质量的原因,借助Matlab软件建立了全电缆电力贯通线的仿真模型,分析验证了全电缆电力贯通线无功补偿的必要性和首端集中+沿线分散补偿方案的有效性,为高速铁路全电缆电力贯通线的设计与建设提供参考。With regard to the problems of terminal voltage rise and low power factor in the operation of high-speed railway full cable power through line,the paper analyzes the reasons that affect the power quality of the through line in principle based on the operation characteristics of high-speed railway full cable power through line,and establishes the simulation model of the full cable power through line with Matlab software,The analysis verifies the necessity of reactive power compensation for all cable power through line and the effectiveness of centralized compensation at the head end plus decentralized compensation along the line,providing reference for the design and construction of all cable power through line of high-speed railway.
