电网分压线损率计算方法

Calculation Method of Divided Voltage Line Loss Rate in Power Grid

电网线损率是电网企业的一项重要综合性技术经济指标。以分压线损率为理论依据,利用指标关联关系和电网设备拓扑关系信息,提出了一种分压线损率可直接计算的新方法,即"分压线损率计算法",并建立了数据平衡关系的校验机制。该方法仅利用统计的单电压层线损率,即可计算任意电压层及以上或以下线损率,不再需要花费大量精力分别构建复杂的统计模型,为线损决策分析、异常数据校验等提供了方法和依据,方便快捷、简单实用。

Line loss rate is an important synthetic technological and economic index for electric power supply companies. Based on the theory of divided voltage line loss rate and by applying the information of topology, a new method, i.e., algorithm for calculating the divided voltage line loss rate, is proposed in this paper. A check mechanism of data balance is set up. This method can calculate any voltage levels by using only the statistics of single level voltage line loss rate and no separate statistics models are needed. The method is simple and quick in calculation and can provide a basis for analysis of line loss and check of abnormal data.
