Abstract

In To improve the accuracy of the state assessment of overhead transmission lines

the sensitivity of the parameters which can reveal transmission line state is analyzed

and a state assessment index system of transmission line is constructed based on principal component analysis.Then a new state assessment method based on the Bayesian network is proposed

and a mathematical model of the Bayesian network is established.Examples verify the feasibility of this new state assessment method.Based on the multiple source data platform

an expert system of transmission line state assessment is designed to implement the assessment.The results show that the assessment index system is more objective

and the state assessment method is effective and feasible.
