Research And Design Of Distribution Network In Yinan County

With the increasing scale of our country's electric power network,the network structure is more and more complex,the user's demand for stable power supply is getting higher and higher.This requires the failure of the normal operation of the power network to eliminate the occurrence and failure in the network,to quickly and accurately locate the fault location,quickly troubleshoot to ensure the normal operation of the network system to improve system reliability and minimize losses.With the rapid development of China's economy,the differences of power grid development are highlighted,and the regional electricity demand and demand are in urgent need of statistical planning.According to the Technical Guidelines for Planning and Design of Distribution Network,it is urgent to solve the regional power grid planning.Therefore,it is of great significance to study the demand of specific power network planning in each region.The purpose of this thesis is to guide the rolling planning of distribution network in various regions of the company operating area,which is suitable for power supply enterprises under county level.District companies under the jurisdiction of the district companies can refer to this paper.According to the requirements of the rolling plan of the distribution network of the Company,the paper fully absorbed the relevant contents of the "Technical Guideline for Distribution Network Planning and Design".Content can be based on actual needs,appropriate to increase the content and depth.In the preparation process also take into account the differences around the development of power grids.National economic,equipment capacity,power,reliability and other statistical data have been marked the original data sources.The scope of the planning for the company operating area of public power grid.Ie the power grids funded by the grid company.110 kV power grid in principle by the State Grid Corporation of investment;35kV and below the power grid investment,direct supply companies and holding companies are incorporated into the company's investment,county companies can take charge of county-level enterprises to consider self.
