Reliability Analysis And Research On Distribution Power Supply Of Nanchang County

Power supply reliability is a basic indicator,can show the operation of the power system and power management level.At the same time for the grid planning and maintenance and maintenance and equipment operation and so has an important guiding role.Distribution network is to contact the user and the power system of the intermediate links,distribution network power supply reliability is a measure of power quality is very important factor.Through the analysis and research on the reliability of power supply,it is found that the distribution network is relatively weak link,contact the local economic development,develop measures to improve the reliability of power supply,which can provide better quality of power and create higher social benefits.In this paper,the power supply reliability of distribution network in Nanchang County is analyzed.First,the reliability of power supply at home and abroad is analyzed,and then the basic theory and analysis method for the reliability of distribution network are introduced.The focus is on Nanchang County distribution network analysis of the status quo,Nanchang County,the distribution network problems.This paper mainly analyzes the distribution of power distribution from the Nanchang County,the distribution of the medium voltage distribution network and the reliability of the power supply,and analyzes the reliability of the distribution network by using the gray relational analysis,which can be analyzed by combining the distribution of the distribution network Influence of Factors in Distribution Network on the Reliability of Distribution Network in Nanchang County.And then establish a simplified model to predict the reliability of distribution network.From the essence of reliability calculation model,the definition of distribution reliability rating index is given.Through the development of Nanchang County distribution network reliability rating method,reflecting the Nanchang County distribution network level and can guide the construction network investment.The reliability of distribution network is affected by many factors.Through the analysis and research of this paper,the weak link of distribution network in Nanchang County and the main factors affecting the reliability of power supply are analyzed.So as to develop these measures to improve the reliability of distribution network power supply in order to achieve the purpose of improving the reliability level of distribution power supply in Nanchang.
