摘要
架空输电线路的运行状态直接影响着电力系统运行的可靠性,为了正确的评估运行中架空输电线路的可靠性,提出了一种基于贝叶斯网络架空输电线路运行状态评估方法。基于Bayes网络建立的架空线评估数学模型不仅可以得出输电线路及各部件的4种运行状态概率,还可以很清楚的看到各部件对输电线路运行的影响,便于线路的状态检修,另外,针对传统传统的重要度计算过于主观或客观的不足,在计算权重时提出了一种主客观赋权法。通过实例计算验证了该模型的有效性。
The running state of overhead transmission lines directly affects the reliability of the entire power system op- eration. In order to assess the reliability of the running overhead transmission lines correctly, a method for operation state evaluation of overhead transmission lines based on Bayesian network was presented. The math model of the evaluation of overhead transmission lines based on Bayesian network can not only carry out four kinds of the state probability of over- head transmission lines and each part of lines but also can see the impact of every component of overhead transmission lines clearly, which is easy to the state maintenance of overhead transmission lines. In addition, aiming at the shortcoming of subjective or objective method of the importance calculation, proposes a subjective and objective method to calculate the importance was proposed. The evaluation method can make correct assessment according to the calculation of a exam- ple.
