摘　　要：建立了韶山 型 (SS1 )电力机车运动过程的动态数学模型 ,提出了一种计算电力机车各次谐波电流概率分布的方法。在数学模型中模拟了机车从启动、加速、调整、制动直至停止的全过程 ;根据韶山 型电力机车的特点和实际运行情况 ,考虑了机车运行的不确定性 ,把主要的随机变量引入数学模型中 ,用蒙特卡罗法对机车的随机模型进行数值计算。韶山 型电力机车的各次谐波电流概率分布算例的计算结果表明了该方法的有效性。A dynamic model for simulating the operating process including starting, accelerating, regulating, braking andstopping of type-SSI electric locomotive as well as its speed and traction characteristic is developed. According to the featureand the realistic operating condition of type--SSI electric locomotive. the uncertainty factors of the electric locomotive areanalyzed. An approach for calculating the probabilistic harmonic current is proposed by introducing the random variables intothe dynamic model and by using Monte Carlo simulating method. The probabilistic distributing results of harmonic current oftype-SSI electric locomotive show its effectiveness.This project is supported by National Natural Science Foundation of China (No. 59737140).
