Research On Distribution Network Planning And Optimization Design Of Guyang County

Over the past 30 years of reform and opening up,the national economy has achieved rapid development,and China's GDP has leapt to the world's top second,becoming the world's second largest economy after the United States,the world's second largest economy.The development of economy promotes the creation of high and new science and technology,and the high technology plays an important role in promoting the economy.Therefore,in the process of power use,power load also showed a gradual upward trend,the effective supply of national strong need for electricity,power grid structure,forcing manufacturers to establish a complete update of power equipment,new substation.Among all the problems that need to be solved,the scientific and effective planning of power grid construction is the most important,which has attracted the attention of experts in the field of electricity.With the widespread use of electric power in the national life,the operation of the power industry is not only related to the interests of the business,but also closely related to the public life.Power supply enterprises must take certain measures to meet the people's demand for electricity.The first thing to do is to expand the scale of the power system is the scientific planning of power systems,in the long run,this important part of the power industry is the key to the success or failure of the operation.At present,the overall level of Guyang County distribution network equipment is relatively backward,the old line and distribution accounted for relatively large,aging equipment and other problems,especially the low voltage power supply ability and quality can not meet the needs of users,frequent power outages and low voltage problem.According to the actual situation of Guyang county power supply area,combined with the tourism service industry,the agricultural load as well as the rapid economic development of mountain area and mining area.The purpose of this paper is according to the relevant standards and technical transformation of the distribution network,combined with the actual operation experience,studying how to use ant colony optimization algorithm to solve the optimization problem of network structure,to meet the demand in low voltage distribution network load growth,improve the power supply reliability and power quality.
