Research On Theoretical Line Loss Calculation And Loss Reduction Strategy Of Distribution Network

Line loss rate is an economic indicator.It can reflect the planning and design level of power grid,the production capacity of power grid and the management level of power workers.Controlling the loss rate of distribution line in a suitable numerical range can reduce the loss of power energy in the transmission process,save money for power customers and increase economic benefits for power supply companies.In accordance with the requirements of building a conservation-oriented society and environment-friendly enterprises,power supply enterprises,as the main body of the implementation of the national energy strategy,are responsible for ensuring the modernization of energy resources allocation and meeting the power demand of rapid economic and social growth.Power supply enterprises should follow the law of power grid development,improve power grid structure,strengthen enterprise management,reduce power grid losses,actively adopt energy-saving,land-saving,water-saving equipment and technology,improve energy efficiency,and serve harmonious social development.At present,the management of line loss rate in our country is only in the middle level in the world,and there is still a big gap compared with the developed countries.Therefore,it has great potential to optimize the operation of power grid dispatching by using modern management means to realize low-loss transmission of power grid.In this paper,based on the actual situation of distribution network operation in Yishui Company,various methods of theoretical calculation of distribution network are compared,their advantages and disadvantages are briefly analyzed,and the calculation method is improved.On this basis,the theoretical calculation program of distribution network is compiled,the theoretical line loss of Yishui Company in 2018 is calculated,and the calculation results are analyzed,and the feasible scheme of reducing line loss target in 2019 is put forward.Finally,the actual situation of line loss management in Yishui Company is deeply studied,and the measures of reducing line loss in management and technology are put forward.The purpose of this paper is to provide references for power supply companies in order to reduce the loss of electric energy in distribution network and achieve the purpose of reducing loss and strengthening the power supply capacity of power grid...
