摘　　要：本文运用马尔柯夫理论建立了一种考虑天气影响的架空输电线路可靠性评估数学模型。该模型将输电线路的运行状态划分为四种状态,给出了每种平稳状态的状态概率、状态频率和状态持续时间的计算方法。实例分析验证了本文提出的模型及算法的正确性。Based on Markov Model, a mathematic model of reliability evaluation of overhead power transmission line is established in this paper. In this model, running state of transmission line is divided into four states, and calculation method of state probability, state frequency and state duration in balanced state are given. Example analysis has proved that the model presented here and the arithmetic is correct.
