摘要
同塔多回输电线路由于共用基础、杆塔,共有一个通道环境等,状态情况有诸多共性。基于此,建立一种新的基于贝叶斯网络的输电线路评估状态模型,综合考虑其历史状态和当前状态以及预测状态,并通过样本参数学习,结合GeNIe软件不断丰富贝叶斯网络条件概率,有效地提高智能化评估输电线路综合状态的准确度。实例验证,该方法准确、有效、实用,可以大幅提高同塔多回线路状态评估的效率。
The multi-circuit transmission lines on the same tower due to have the common foundation,tower and the common channel environment,and the state conditions have many commonness.Accordingly,a new Bayesian network based evaluation state model of the transmission lines were established,which comprehensively considered the historic and current state and the predictive state were comprehensively considered.Through the sample parameter studying and combining with the GeNIe software,the conditional probability of Bayesian network were gradually enriched,and the accuracy of integrated conditions of intelligent evaluation transmission line was effectively improved.The examples verified that the method is accurate,effective and practical and can significantly improve the efficiency of the condition evaluation of multi-circuit transmission lines on same tower.
