【摘要】 评估输电线路状态对于实现输电线路的智能运行具有重要作用。提出了一种基于自反馈双向贝叶斯网络的输电线路状态评估的新方法,建立了输电线路贝叶斯网络状态评估的数学模型,给出了评估的思路与步骤,条件概率的求法,得到了线路与各个部件处在正常、注意、异常与严重四种状态的概率,并通过实例进行了验证。更多还原

【Abstract】 The state evaluation of the transmission line has an important role to implement its intelligent operation. A new state-evaluating method of the transmission line based on the self feedback bidirectional Bayesian network is proposed, and the mathematical model of the Bayesian network is established, the ideas and steps of evaluation and the method for conditional probability are introduced,the four probability such as normal, abnormal advertent, and serious of transmission lines and its various parts are obtained. The feasibility of this new method is verified by the examples.更多还原
