Study On The Planning Of Power Distribution Network In Si Hui City Fine Chemical Industry Park

Economic development,electricity first.In the process of rapid urban development,the power demand is also gradually expanding,especially the medium voltage distribution network.In the infrastructure of urban industrial development,it is very important to improve the urban power planning,which can not only guarantee the security and stability of power supply,but also make rational use of social resources and obtain greater social benefits.At present,however,the construction of medium voltage distribution network in China lags behind the speed of economic development.Therefore,it is imperative to perfect urban power planning.In view of the accelerated development of large industrial parks in sihui city in recent years,the medium voltage distribution network of jianggu town in sihui city has been unable to meet the needs of further development of large industrial parks in both function and scale.The general urban planning of sihui city(2010-2030)determined to expand the central development belt of sihui,build jianggu town into a sub-center of the city and become a new important growth pole of sihui economic development.This paper fully understand the status quo of the distribution network planning research at home and abroad,combined with the actual situation of sihui fine chemical industry park,combined with sihui of fine industrial park grid calculation and analysis of present situation and the historical data,using the method of calculation and analysis of scientific theory to study,points out that the current sihui regional power grid planning is difficult to fundamentally solve the leap-forward development of power demand and the contradiction between the existing grid power supply ability is insufficient,and can't meet the region's large industrial park,technical index of reliability of power supply quality problems and the status quo,and analyzes current situation of the development of industrial park.Finally planning scheme combining industrial park planning and forecast each block,power supply in the central vision of saturated load,according to the construction plan and the present situation of source distribution network line structure,the corridor and the load distribution,this paper analyzes the regional power grid planning objectives,priorities and principles,and on this basis and the reference,put forward in the near future and forward the power distribution network frame structure scheme,and the key planning recent rack constructionrenovation plan,to guide the development of the spatial grid structure present situation to the long-term goal of the spatial grid structure transition,and the effect of the implementation of the scheme,including line to evaluate the load rate,risk analysis,etc.The planning of medium voltage distribution network in the industrial park will be improved and improved,so that it can be provided with reliable power supply and economic efficiency,so as to meet the needs of construction and economic development of the whole region and even the whole city,so that the power can better serve the social and economic development of the region.
