摘　　要：在分析比较电能量采集系统(TMR)和能量管理系统(EMS)数据特点的基础上,结合计算实例提出了线损法和功率法两种电量追补的计算方法。对两种计算方法的相对误差进行了分析,并结合误差曲线提出影响计算结果的关键分量。该方法可操作性强,计算结果可靠,在多起电量追补计算中得到应用,取得了较好的效果。Based on the analysis and comparison of the data features of power energy data acquisition system ( TMR) and energy management system ( EMS) , two power energy reclaiming method, line loss rate method and power meth-od, are proposed in this paper with calculation examples. Relative error performance analysis is also conducted, and key aspects contributing to the error of calculation results are pointed out according to relative error curves. These sim-ple and reliable methods have been utilized in many power energy reclaiming calculation cases, and striking effects are achieved.
