摘要
分析了在高速铁路常用的供电方式下,即带回流线的直接供电方式和AT供电方式下的接地回流情况,通过对2种供电方式下牵引网的等效电路建模、计算,得到钢轨电流和地中电流分布系数的近似计算公式,并对回流情况进行了分析。
This paper analyze the earthing and return of power supply for high-speed railway under different power supply modes including the DN power supply mode with return-circuit and AT power supply mode. The paper analyzes the return-circuit and get the approximate formula of rail-circuit and earth-circuit distribution coefficients by modeling and calculation for the traction power network equivalent under the two power supply modes.
