摘　　要：推导了多辆电力机车运行条件下电气化铁道牵引变电所谐波电流计算公式 ,考虑了电气化铁道操纵规程对谐波的影响 ,设计了相应的数据库存放牵引负荷谐波仿真计算所需要的信息。文中所开发的仿真软件能够依据铁路部门的运行图和操纵图 ,结合电力机车谐波电流动态仿真计算模型 ,考虑牵引负荷主要的随机因素 ,利用蒙特卡罗法得到牵引变电所高压母线全天 2 4 h谐波电流的概率分布和统计特性。A new form ula is presented to obtain the harmonic current at the traction substation under the condition of multiple locomotives in operation. The influences of the operating code for electrical railway on the harmonic are considered and the corresponding database has been designed for storing the information needed by sim ulation calculation of the traction load harm onic.The sim ulation software developed by the authors makes it possible to obtain the probability distribution and statistic characteristics of the traction substation's high- voltage bus around- the- clock harmonic currentin accordance with the railway department's running and operating chart,referring to the m odel for dynamic simulation calculation of the harmonic current for electric locom otive,taking into account the main random factors of the traction load and making use of the Monte Carlo analysis.
