Study On The Feeding Modes Evaluation Index System And Method Of Urban Distribution Network

With the rapid development of the national economy,urban distribution network as an important component of power system receives widely attention.The state has invested a lot of money to it.Medium voltage distribution network plays an important role in urban power grids.Medium voltage power feeding mode has a direct impact on system reliability and the user's consumption level.Rational and effective use of the power supply mode can improve the quality of electricity supply system and access to good social and economic effectiveness.This paper has summarized all kinds of domestic and foreign supply modes,established urban medium voltage power distribution network mode evaluation system,introduced the computational method of 9 evaluating indicators in detail,pointed out the insufficiency of the classics DEA model which exists in the multi-plan multi-index quality synthetic evaluations By the step-by-step improvement to classics model,this paper finally has put forward a new way in soveling evaluation problem based on AHP and the DEA method which has been proved effective and feasible.
