接触网分布参数对供电系统功率因数的影响

常规牵引供电系统分析在采用集中参数模型时,往往忽略导线分布参数影响,难以准确评估不同列车对数下客运专线功率因数.本文运用导线分布参数,建立了供电系统仿真模型,运用该仿真模型对不同发车密度下客运专线功率因数进行了定量计算;最后对某客运专线进行了实际测试,测试结果验证了模型的正确性,可以指导工程设计和运营维护.

Influence to Power Supply System Factor Caused by Overhead Contact Line Distribution Parameters

The concentrated parameter model is mostly used for analysis of routine traction power supply system,it will neglect usually the influence of the distribution parameter of the conductor and it is difficult to assess accurately the power factor of the passenger dedicated line with different pair of trains. The paper illustrates that the power supply system simulation model is established by means of conductor distribution factor and it will calculate quantitatively the power factor of the passenger dedicated...
