Fuzzy evaluation method of directional weight overhead transmission lines based on grey correlation analysis
In order to accurately grasp the structural health state of transmission lines,a fuzzy evaluation method of directional weight overhead transmission lines based on grey correlation analysis is proposed.In this method,a fuzzy evaluation system is established through the key deterioration factors,and based on the historical data of the region to be evaluated,the directional weight set for the region is constructed by the grey correlation analysis method.Meanwhile,the state distribution is characterized by the improved triangular trapezoidal membership function,and the intuitive engineering assignment results can be obtained.The case analysis shows that the evaluation method is conducive to accurately evaluate the actual operation state of transmission lines,and can guide the condition based maintenance.
