It is the premise and foundation for the implementation of the maintenance work to timely and accurately understand the status of the distributed power load lean conversion device.Under this background,a linear weighted evaluation model for abnormal state of distributed power load lean conversion device is studied.On the basis of the preliminary selection of indica-tors,the cumulative contribution rate of each assessment indicator is calculated,and the indicators with a cumulative contribu-tion rate of 85%or more are selected as the final assessment indicators to build an assessment indicator system.The improved analytic hierarchy process is used to calculate the index weight,and then the index score is multiplied to obtain the state score of the distributed power load lean conversion device.The degree of abnormality is determined by comparing the state classifica-tion standard.The comparative experimental results show that this method can effectively evaluate the abnormal state of the distributed power load lean conversion device,and the accuracy rate is up to 99.2%.It provides a reference for improving the operation quality of the device.
