Research On Medium And Low Voltage Distribution Network Planning Of Dongguan City Bridge Town In Thirteen Five-year Plan Period

Power network planning is one of the most important parts in the power system. It must be scientific optimization planning in order to ensure the rationality power regenerate and the safety and economy of the power grids, as well as improving power quality of distribution network. The Bridge town is located in Dongguan city east, where is well placed for easy access and perfect matching facilities and convenient transportation.The Bridge town is positioning the country’s comprehensive strength thousand town and Lotus town Chinese, which district puts great emphasis on real estates and industrial park the third sector. And thus the capacity of electric supply must be strengthened. The planning on medium and low voltage distribution network then becomes very important.In this paper, first of all, based on the research of the Bridge town economy development situation, It analysis the Historical electricity demand and situation of Medium and Low Voltage Distribution Network.The Summary main problems of grid and causing and a plan to solve.Secondly, It’s used reported loading method combined with annual rate of growth and maximum load utilization hours.According as the forecast Bridge load level year by year, and refer to the local economic development planning and key regional planning and major project construction progress. Which request to predict the network load and pass verification to gained a rich supply of the next year the load data.Again, this work combined with the results of the superior substation planning and power supply range to obtain the Medium and Low Voltage Distribution Network lanning scheme. it is get the focus of the low voltage distribution network project planning from 2015 to 2015 years with analysis the scheme.Finally, this work based on Infrastructure project progress and scale of construction and Investment unit price to the total investment Medium and Low Voltage Distribution Network of Dongguan City Bridge Town in Thirteen Five-year Plan period. Then the word to analysis the existing problems and reliability andLoss rate index in Bridge town’s grid.
