Planning Of Distribution Network In Jiaozuo City

Electricity is an important factor to measure the development of urban economy, and the scientific and reasonable power grid planning can get great social and economic benefits. Jiaozuo, with a large population, with the accelerated process of urbanization, the proportion of industrial and residential electricity will continue to steadily improve. The city as a regional economic and social development of the leading, the power grid planning not only affects the safe and stable operation of the whole power grid, but also related to the coordinated development of all sectors of society, government departments. For urban distribution network construction and transformation of the work, it is necessary to give full consideration to the existing network and load prediction effect of planning, in-depth and detailed analysis and understanding of the existing network, as far as possible to grasp the regional planning in the future load growth trends and information, using a variety of calculation method of regional planning load growth and make accurate and appropriate estimates.Many factors affect the load changes of city power grid, compared with the large power grid load, the volatility of city power grid more and more micro factors. Therefore, this thesis is on the basis of participating in the Jiaozuo power supply area "the 13 th Five-year network planning", in Jiaozuo City distribution network planning as the background, combined with economic development planning of Jiaozuo City, Jiaozuo City Distribution Network of and analysis of the existing problems, the "big user + natural increasing rate method prediction scheme, determine to 2014 as the base year, respectively in Jiaozuo City electricity load were 2015-2020 year by year load prediction. Study on the core part of power grid planning namely substation distribution network planning design and analysis. According to the typical investment list of distribution network in Jiaozuo city 2015-2020 year investment volume, the total investment of 1 billion 380 million yuan. So that the results of the network planning has more realistic significance.
