【Abstract】 Based on the basic theory of Markov processes and the properties of transmission frequencies among cumulativestates. the mathematical model of HVDC transmission system is established. The method to obtain its equivalent model isgiven. The equivalent transitional rate is obtained by boundary wall. Using this equivalent model, the order of the stochastictransitional probability matrix is reduced: the calculation is simplified with high accuracy. A practical example proves that themethod is correct and effective.更多还原
