Distribution network uninterrupted operation is a key measure to improve the business environment and power supply reliability.In order to reasonably evaluate the uninterrupted operation capacity of the regional distribution network

firstly

the evaluation index model of the distribution network uninterrupted operation is constructed by using the chromatographic analysis method.Based on the theory of principal component analysis

it reduces and de-correlates the evaluation indexes in uninterrupted operation of distribution network.Secondly

it generates a new evaluation index system of principal component evaluation index.The efficiency value and target value of each index are obtained

which provides a basis for decision-makers to accurately implement policies.Finally

based on the development status of uninterrupted operation in a provincial distribution network

it verifies the objectivity and scientificity of the evaluation method

and provides some references for the evaluation system of distribution network uninterrupted operation.
