The Characteristic Of Distribution Power Network Planning In Downtown And Its Application In Wangjian Of Dongguan

With the development of national economy and the improvement of people’s livingstandard,the demand for electricity is inereasing. Now the electric power system of Wangjianis difficult to meet the growth load. In order to ensure the sustained development of nationaleconomy in future,power distribution planning, construction and renovation work arebecoming more and more important for the decision makers. As the power networkconstruction involves a large amount of money and land requisition matters, how to do welldistribution planning,ensure the safe, stable, reliable and economic operation of distributionnetwork, play the efficient use of funds and the expropriation of land to achieve maximumefficiency, are one of the indispensable and important work to the relevant government andelectric power enterprise.This paper is in the "12th Five-Year Plan" based on the calculation of power gridconstruction, analyzing the situation and historical data of Wangjian, it obtains reasonableload forecasting and110KV and above substation planning scheme, and supply relevantsuggestions for main network. It divided the scope of power substation reasonably,recommended a medium voltage distribution network construction scheme, and provide thebasis for Wangjian’s future power construction, modification and optimization. The planningwill be further improve the distribution network of Wangjian, and make it meets the needs ofthe town construction and economic development, and be high power supply reliability andeconomical operation of modern power system.
