摘　　要：根据区域电网的特点,提出电能损耗递推预测法,采用状态波动系数建立省间交换电量和线损电量、线损率之间的联系,综合考虑负荷形状系数、等值电阻、平均电压、运行时间、功率因素等方面对线损的影响,在省间交换电量预测的基础上实现线损电量和线损率的预测,为电网节能降损及经济运行提供参考。Based on the characteristics of regional power grid, proposed grid loss rate recursive forecasting method, using state of fluctuation coefficient to establish the link between inter-provincial exchange power, grid loss power and grid loss rate.Taken comprehensive consideration of load shape factor, equivalent resistance, average voltage, running time, the power factor etc to the impact of grid losses,based on the inter-provincial exchange power prediction, forecasting the grid loss power and grid loss rate. Providing reference for grid Loss Reduction and grid economic operation.
