利用多导体传输线理论，建立牵引网多导体传输线等值模型，计算牵引网分布电容。以牵引变电所实测数据为基础，计算全天功率因数实测值，结合牵引网分布电容和牵引变电所全天功率因数表达式，计算全天功率因数理论值，并分析牵引变电所功率因数的影响因素。理论分析表明，在线路负荷较小时，牵引网分布电容产生的容性无功功率对变电所功率因数有很大影响。

The traction was established based on multi conductor transmission line theory, multi conductor transmission line equivalent model, calculation of traction network distributed capacitance. In traction substation based on measured data, calculate measured throughout the power factor, combined with traction network distributed capacitance and traction substation round-the-clock power factor expression, calculate the theoretical value throughout the power factor, and analyzes the influence factors of power factor of the traction substation. Theoretical analysis showed that the line load is small, traction network distributed capacitance of capacitive reactive power has a great influence on the substation power factor.
