A Study On The Impact Of 10kV High-loss Line Modification On Line Loss In Xinmin Area

Power loss rate(usually abbreviated as line loss rate),as one of the key economic indicators for power supply companies,represents the comprehensive capability of planning,operation and maintenance and management of regional power grid.The energy in power grid is to meet the customer’s demand by relying on subsequent transmission,transformation and distribution procedures.During the transmission of electricity,there is a certain amount of power consumption of each type of component and equipment in the power grid system.In the current line loss system,the line loss of 10 k V distribution network accounts for the main part of all line losses.In actual marketing activities,it is necessary for power supply companies to actively carry out line loss calculation and research activities.The purpose of carrying out related work is to solve the problem of power loss,achieve more ideal energy saving effect,and enhance the overall benefit of the company.The calculation of line loss should be based on corresponding theoretical analysis,matching theoretical analysis procedures,and collected data in order to accurately analyze the theoretical line loss parameters.Only on this basis can the follow-up work be effectively carried out.This study analyzes and compares several commonly used line loss analysis schemes,and discusses and compares various calculation schemes for distribution network line loss.It obtains a new scheme for analyzing theoretical line loss in Xinmin area.Based on theoretical analysis and collected data,this study further discusses macro measures of reducing rural power grid line loss.It also proposes specific measures for achieving lean transformation of high loss line in Xinmin area from the perspectives of upgrading power grid voltage,replacing conductor cross section,economical operation of transformer,and technical transformation of distribution network.This research is of great theoretical and practical significance to controlling the actual line loss rate parameters,reducing the existing loss of electric energy,increasing the comprehensive power supply capacity,strengthening the economical operation of power grid,and continuously enhancing the power supply service offered by Xinmin Power Supply Company and other rural power enterprises.
