| The urban power distribution network is a necessary infrastructure and energy supply system for the city,which has a direct impact on the safety and reliability of the city’s power supply.The county power distribution network is the end of the power supply and will directly contact users,and at the same time will be closely related to the development of the county’s economy and the improvement of people’s living standards.In recent years,my country’s economic development has become more and more rapid,and the demand for electrical energy is constantly increasing in terms of commerce,industry,or residents’ lives.With the continuous increase of county load,the power supply capacity of the county power distribution network will increase accordingly,and the investment scale of the distribution network will become larger and larger.How to accurately invest and produce results has become an urgent problem to be solved.This article will study the optimization of the power supply indicators in Jinxian County on the basis of the grid planning.This article first introduces the basic theories of grid planning for distribution networks,including models and basic principles,Then the composition of the power supply index of the distribution network and its optimization direction are explained,mainly from how to optimize the index of the distribution network grid structure,operation level,and equipment level.Then,grid planning was carried out to optimize the power supply index of Jinxian County,and the power grids below 10 k V and 35 k V and above were planned through short-term and long-term load forecasting.Finally,the power supply indicators of Jinxian County in the current year,transition year and saturation year were evaluated.By using the Delphi method to assign weights to the indicators,the evaluation conclusions of the power supply indicators were drawn. |
