摘　　要：由高电压等级发电厂关口计量装置的设置情况,以及发电厂主要统计的电能经济指标,提出当某电能计量装置故障,造成其所计量的电量出现差异时,可以通过某一经济指标的正常统计值推算出异常电量的正常电量值,并结合实例分别介绍利用发电机升压变压器变损率计算关口差错电量、利用综合厂用电率和发电量计算关口差错电量的方法。This paper presents the setting of pass electricity metering device in high voltage level power plant, and electricity energy economy index points out while electric quantity is difference during electricity energy metering device in trouble, the proper electric quantity can be calculated through the proper statistic of some economy index, and this paper also introduces the methods that pass error electric quantity is calculated through transformer loss rate of generator step-up transformer, through auxiliary power ratio and generation quantity.

关 键 词：关口电能计量 计量装置故障 差错电量 变损率 厂用电率
