Midium And Long Term Planning Research Of YingCheng Power Grid

With the rapid development of the Ying Cheng economy,the safety,reliability and higher requirements of power supply are put forward.Power grid planning is an important component of the power planning.the scientific and reasonable planning can guarantee the power system security,stability,economic and reliable operation,at the same time,it can maximize saving state infrastructure resources,and obtain great economic and social benefits.In this paper,the current situation of Ying Cheng power grid is sorted out,and after sufficient systematic analysis and comparison,it is determined that the high voltage site station and the high voltage grid and the route corridor are determined.First of all,This paperintroduces the planning background,scope,number of years,thinking and research emphases of power grid planning,and then investigates the economic and social development of urban areas,and systematically sorts out the current equipment,network structure and operation of the urban distribution network 220 k V and above,110 k V and35 k V,etc.,points out the existing problems.Secondly,combining with the present situation of municipal and municipal planning,following energy policy under the guidance of state plans,taking overall consideration of various factors,the paper develops a scientific and reasonable Ying Cheng high-voltage power grid development planningwhich is based on Ying Cheng power load forecastingand the balance of power supply and demand of each voltage grade..Finally,this paper discusses the social and natural influences of the grid planning and puts forward some solutions according to the problems.In this paper,high voltage power grid planning focus reflects the modernization of power grid construction requirements constituting “power capacity is enough,system security and stability,flexible,strong network and the operation of the equipment with advanced specifications",it could fully provide strong reference for urban power grid planning.
