Reliability Evaluation of Distribution Transformer Operation Based on Multiple Feature Quantities
The reliability assessment of healthy operation of distribution transformers is of great significance for achieving active operation and maintenance,ensuring reliable and high-quality electricity consumption for the people,and safeguarding high-quality economic development.This article proposes a multi feature quantity reliability evaluation of distribution transformers based on daily monitoring methods and data of distribution networks.Firstly,a reliability evaluation system for distribution transformers is constructed from three aspects:electrical quantity,environmental quantity,and state quantity,and the definitions of each indicator are provided;Secondly,a method for calculating the weight of indicators based on the integration of subjective and objective factors was proposed,and the scoring principles for each indicator were given.A reliability evaluation process was designed;Finally,the feasibility of the indicator system and method proposed in this paper has been demonstrated through practical case analysis,which is beneficial for achieving health monitoring and active operation and maintenance of distribution network transformers,and has important value in improving the operational reliability of distribution network transformer equipment.
