Study On Comprehensive Evaluation Of Distribution Network Planning In Yongning County

The development of social economy can not be separated from the support of power construction, while the power grid construction is an important part of power construction, and has become the important factor to restrict the development of local economy.. In order to ensure a rapid and healthy development of the local economy, it is necessary to make the speed and quality of power grid construction to keep up with the situation of local economic development, it is necessary to more scientific and reasonable construction of strong smart grid. Grid system including power generation and supply system, the power supply system is divided for transmission, substation, distribution system, and as ultimate end-user benefit, distribution system is one of an important part of the power grid construction, the planning and design work is especially outstanding and important to must from the point of view of the network economy and economic benefit and social benefit, more comprehensive analysis of distribution network planning of science and rationality, so as to ensure the distribution network planning and local development to be closely integrated. However, in the current distribution network planning content, effect evaluation mainly concerns most are placed in the lay in the analysis of the economic benefits of the power grid equipment investment, and lack to analysis and evaluation of other factors which affect the power grid construction, also due to the lack of scientific and reasonable index analysis method, which seriously affects the integrality and scientific of the distribution network planning evaluation.This paper expounds the related theories and methods of distribution network and distribution network planning evaluation system, in based on the comprehensive analysis of Yongning County distribution network construction which brings to the regional development of the social benefits of the established influence of Yongning County distribution network planning index system corresponding to., in close connection with Yongning County distribution network and Yongning County Regional Development of the actual situation, through the analysis of the index weight by AHP and entropy weight method, finally by combination weighting method, indicators are determined, and then through the fuzzy comprehensive evaluation method to evaluate the effect of Yongning County distribution network planning, and puts forward the scientific and reasonable construction of opinion, for the preparation of Yongning County Thirty-fifth distribution power grid plan to the guiding role.
