引入母线不平衡率的分压线损率统计方法

Statistical Method for Partial Pressure Line Loss Rate Based on Bus Imbalance Rate

对变电站母线电能量不平衡率产生的原因进行了分析,分别考量计量设备系统倍率设置错误、计量回路二次压降、抄表因素、电气设备运行状态、计量设备固有误差对其影响。并引入母线不平衡率的分压线损统计方法,精确统计分压线损,以更好地分析相应电压等级的电网损耗。

This paper analyzes the reasons for substation busbar power imbalance rate, as well as the impacts of ratio setting errors of measuring equipment system, secondary voltage drop of measurement circuit, meter factor, electric equipment running status, the inherent error of measuring equipment. And the statistical method for partial pressure line loss rate based on bus imbalanee rate is adopted to make aeeurate statisties of partial pressure line loss in order to better analyze the loss of power grid of the eorresponding voltage level.
