The Voltage Passing Rates Analysis And Improvement Of Xinyi Low Voltage Network

XinYi city, situated in the southwest of guangdong, to 50 mountainou area of guangdong province (city). Within the territory of more than seventy percent is mountain, known as "eight mountains monohydrate a minute field", high terrain northeast, southwest low, mainly mountainous topography, within the territory of mountains, rivers and height from 50 meters to 1704 meters above sea level. Influenced by topographic factors, fragmented XinYi region of the people live, load distribution, has the certain difficulty, power grid construction and historical reasons, XinYi grid development is slow, compare travel-weary equipment, low voltage area.Voltage percent of pass is one of the important indicators of the quality of voltage, is one of the important reflect to customers to provide quality services. With the development of the society, power users for the requirement of increasing the voltage qualification rate. In recent years, XinYi economy and present the good momentum growing year by year, annual GDP growth rate of 14.2% between 2010 and 2014. As XinYi region’s rapid economic development, residents’ living standard unceasing enhancement, and electrical appliances to the countryside in countries such as preferential policy, a large number of home appliances into the ordinary people, not only increase the demand for electricity, at the same time, it puts forward higher requirements on power supply qualified rate. The current low voltage qualified rate and the increasing electricity demand contradiction is more and more highlights, customer satisfaction is declining. How to solve the problem of low voltage qualified rate and improve the quality of power supply, demand of improving customer satisfaction is around the corner, so the study of XinYi low power grid voltage qualified rate analysis, put forward the measure of economy, can effectively enhance the voltage qualified rate and put into practice, has good practical significance.In this article, through a large number of collecting, analyzing XinYi DiYaWang from 2012 to 2014, the low voltage area basic information, operation information, the user access to information, customer complaint information, find out XinYi unqualified in low power grid voltage power supply radius is too long, was the main cause of wire diameter is too small, with varactor than small and three-phase unbalanced load rate is too high, lack of reactive power compensation, change gear set is not reasonable, etc., improve voltage percent of pass of management measures and technical measures are put forward, and combined with XinYi demand for the development of the township, provide the basis for planning and investment decisions. Combining with the related research results, select XinYi field power supply bureau red flag no.2, turn over the draft Dong, stone village area of engineering practice, the practice has proved the validity of the method, put forward the overall scheme of low voltage regulation XinYi power supply bureau, in the global promotion, further improve XinYi DiYaWang voltage percent of pass, has achieved certain success, partial application experience in maoming promotion step by step.
