The Research On Reliability And Improvement Of Lufeng Distribution Network

The reliability of distribution network as the basic index to reflect the management level of power Supply Corporation and safe operation level of power system.It gets more and more attention in network planning and design?Equipment Maintenance Opera?making and customer services etc.As one part of the whole power system,distribution system is the most close to customers,that effect on reliability and quality of power supply to user.The purpose of the reliability study is to identify the distribution-network's weaknesses and make improvements,and to provide electric customers with more safe and reliable electric power to get the best economic and social benefits.This paper takes the reliability of Lufeng distribution network as subjects and discusses.Firstly.Introduce the significance of the paper,the studying results in domestic and foreign countries?principle and calculation methods for reliability evaluation,summary the views which have done in this field.Secondly.The thesis gives presentation of Lufeng distribution network from the following aspects.Such as the general situation of electric network and source of power,status-of equipment of electric network and status of Lufeng power supply reliability.Then identify the distribution network's weaknesses.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 Lufeng distribution system and do research.This paper also presents a simplified prediction model for the reliability of distribution network.According to the analysis of the essence of distribution network prediction model pointed out the intention of the reliability level(Grid level index).To formulate method of Classification of reliability of Lufeng distribution network,which can reflect the actual level of reliability and guidance for power grid investments.The reliability is determined by various factors.Through the research,find out the main and minor factors that affect the reliability and identify the distribution network's weaknesses.Some measures to improve reliability of Lufeng distribution network have been proposed in this paper.Such as more investment in power grid construction,normative operation and maintenance management,using technical measures etc.
