| The reliability of distribution system plays a very important role in the production and management of the power system which is connected with customers directly, and also electric utilities and electricity customers pays much attention in it. The purpose of the reliability study is to provide electric customers with more safe and reliable electric power to get the best economic and social benefits.Taking the reliability of Shanwei distribution network as the research object, firstly introduced the power supply reliability of distribution research, the basic theory, evaluation index system and algorithm based on minimal path theory of distribution network reliability assessment. From the introduction of the structural characteristics of distribution network, combined with the actual distribution network in Shanwei, considering the various factors which affect the distribution system reliability, the impact of the various factors can be calculated through grey relational analysis. Then find out the main problems of Shanwei Distribution system and do research, according that put forwards effective measures to improve reliability through the main distribution network-building measures, management measures and technical measures. Besides, analyzed the various measures in detail.There are various measures we can take to improve the distribution system reliability . We can make specific implementation according to the actual situation of the Shanwei distribution network. Through the implementation of measures implemented, the power grid will be with much strong structure, larger capacity and better power quality to supply good, safe and reliable energy to the users. |
