Economic Evaluation Of 10KV Distribution Network Reliability On ZhuHai Electric Power System

Economy and reliability are two very important indicator of the power system in Zhuhai area, two indicators but also contradictory. In Zhuhai, Guangdong Province and Zhuhai power network renovation phase power system planning, how to take into account both the system of power grid reliability and economics of investment, this is a very important and necessary job. Study on reliability of distribution network in Zhuhai's fundamental purpose is to provide safe, reliable electricity supply to the user, with the ultimate aim is to get the best social benefits. Power sector statistics indicate that about 80% more customer interruption is caused by fault in distribution network of Zhuhai, Zhuhai reliability of distribution network for most users, and therefore to assess the reliability of distribution network in Zhuhai, improving the reliability of distribution network power supply in Zhuhai in theory and in practice are of important significance.This article combination Zhuhai distribution grid heavy frame and VC language write program, established has a comprehensive consider Zhuhai distribution grid economic sexual and reliability of assessment method, to out has to reliability cost and reliability benefit phase combination as sought Zhuhai area distribution network optimal of investment policy of target function, used has based on single parents genetic algorithm of 10kV Zhuhai distribution grid of reliability cost benefit analysis method to calculation distribution network of reliability cost benefit analysis, established has a comprehensive consider Zhuhai distribution grid economic sexual and reliability of assessment method, focused on analysis has Zhuhai grid user blackout loss to economic quantitative reliability of index, and comprehensive consider economic investment, and line loss, and maintenance costs,, made has economic total cost of concept, solution has economic sexual and grid reliability Zhijian of contradictions.Zhuhai economic and typical connection mode of distribution network reliability evaluation and concluded that the choice of the best connection method under different conditions.This paper in Zhuhai, Guangdong Province doing initial research on the basis of distribution network reliability optimization, each of main equipment in distribution network of Zhuhai economic and reliability analysis, simplification of the problem based on some of the more general conclusion, Zhuhai power network reliability optimization method for further study of the Foundation.
