The dynamic mathematical model of Shaoshan SS1 electric locomotive is established and a method to calculate the probability distribution of each harmonic current of electric locomotive is proposed. According to the characteristics and actual operation of Shaoshan electric locomotive, the uncertainty of locomotive operation was considered, and the main random variables were introduced into the mathematics. In the mathematical model, the whole process of starting, accelerating, adjusting and braking of locomotive was simulated. In the model, Monte Carlo method is used to calculate the stochastic model of locomotive. The calculation results of each harmonic current probability distribution of Shaoshan electric locomotive show that the method is effective.
