计及负荷时序曲线的配电网经济运行负载分析

Economic Operation Load Analysis of Distribution Network by Calculation and Load Timing Curve

传统配电网经济运行分析多仅考虑断面负荷情况下的线损,而在配电网实际运行过程中负荷时刻变化,且年最大负荷相同的不同类型用户其时序特性可能差异较大,这将导致断面负荷下计算得到的最低线损很难指导实际经济运行决策.文章提出了计及负荷时序曲线的配电经济运行负载分析方法,并应用该方法针对不同用户负荷时序特性,计算不同年最大负载率下的配电网综合线损率,为配电网经济运行管理提升提供建议.

The traditional distribution network economic operation analysis more only consider the section load condition of line loss,and in the process of actual operation load changes,and the maximum load of the same different types of users of its timing characteristics may be different,this will lead to section load calculate the lowest line loss is difficult to guide the actual economic operation decisions.Therefore,this paper puts forward the load analysis method of distribution economic operation based on the load timing curve,and applies the method to calculate the comprehensive line loss rate of distribution network under the maximum load rate in different years according to the load timing characteristics of different users,so as to provide suggestions for the improvement of economic operation management of distribution network.
