摘　　要：在并网型光伏系统中,由于并网设备不同,电能计量装置故障会严重影响整体电量计量准确性,传统方法没有对故障类型加以区分,导致带来较大计量误差。提出针对并网型光伏系统故障后的电量计量自动化追补方法。对系统中故障期间电能计量装置的残余电流、残余电压等数据实施缺失数据插补处理。进行电能计量装置的故障分类;根据不同类型故障,估计电能计量装置的自动化追补数据,实现光伏系统故障后的全面电量计量自动化追补。测试结果表明:该方法的剩余电量追补结果接近实际剩余电量,电量计量自动化追补效果较好,且电量计量自动化追补相对误差与绝对误差较低,与实际的追补电量差异较小。In grid connected photovoltaic systems,due to different grid connected equipment,the failure of energy metering devices can seriously affect the overall accuracy of electricity metering.Traditional methods do not distinguish the types of faults,resulting in significant metering errors.Propose an automated compensation method for electricity metering after grid connected photovoltaic system failures.Implement missing data interpolation processing for residual current,residual voltage,and other data of the energy metering device during faults in the system.Classify faults in electrical energy metering devices;Based on different types of faults,estimate the automation recovery data of the electricity metering device to achieve comprehensive automation recovery of electricity metering after photovoltaic system faults.The results of this method are close to the actual residual electricity,and the automatic compensation effect of electricity metering is good,and the relative error and absolute error of automatic compensation of electricity metering are low,there is a small difference between it and the actual charge.
