摘　　要：建立了韶山 型 (SS4)电力机车运动过程的动态仿真模型 ,提出了一种计算 SS4型电力机车谐波电流及其概率分布的方法。根据 SS4型机车的运动方程、控制系统以及整流回路 ,来模拟机车的机械和电气动态过程 ,并考虑了机车运行时的主要随机因素 ,应用蒙特卡罗法 ,得出多辆机车运行时谐波电流的概率分布。计算结果与观音山牵引变电所实测数据相比较 ,统计规律基本相同 ,表明了该方法的有效性。This paper presents a dynamic model of type- SS4locom otive and proposes a m ethod to calculate harm onic currents from the locomotive and their probability distribution.The m odel describing mechanical and electrical dynamic process of the locomotive is based on its movement equation,control system and rectifier circuits.Considering random factors such as the train weight,driver's action and air resistance,the paper uses the Monte Carlo m ethod to sim ulate the probability distribution of harm onic currents under the condition that several locom otives absorb power from the same traction feeder.Com paring the simulation results with those drawn from filed m easurem ent at a traction station is statistically the sam e,which verifies the effectiveness of the proposed m ethod.
