Research On Planning Of Medium And Low-voltage Distribution Network In Jiedonng District

In the past ten years,the state has accelerated the process of urbanization.At the same time as the rapid development of the urban economy,the problem of uneven urban development has become increasingly prominent.In particular,the functions and scale of suburban and county towns cannot meet the long-term development needs.In recent years,many cities have begun to plan to build new urban areas,gradually transfer some functions of the old central urban areas to the new urban areas,and release the development of the old urban areas while building a new urban area that is more in line with modern development needs and has long-term development space.In the overall planning of Jieyang Power Grid,the nearest Jiedong District to the city center will focus on building a new urban area with economic and cultural functions,complementing the functions of the city center and the old city,and enhancing the radiation capacity of Jieyang City Center.In order to meet the future development needs of Jiedong District,it is necessary to plan to build a medium voltage distribution network with reliable structure,sufficient capacity and high power supply reliability.Today,the distribution network has been constructed to a certain extent.This paper investigates and analyzes the status quo of the upper power supply,medium voltage equipment and network structure of the medium and low voltage distribution network in Jiedong District.With reference to the urban planning,current load analysis and industry related standards of Jiedong District,the saturated annual load of each power supply area is expected.Make predictions;analyze the key points,principles and objectives of the distribution network planning in Jiedong District,and combine the network structure,operation status,load distribution and network structure of the superior power supply and medium voltage equipment in Jiedong District,and propose the medium and low voltage distribution in each of the short-term and long-term areas.The planning is aim to build a reliable and efficient distribution network in Jiedong District,which can fit other distribution network construction in other areas.
