110 kV及以下电网理论线损分压指标分析及评价

Analysis and Evaluation on Partial Voltage Index of Theoretical Line Loss for 110 kV and Below Power Grids

根据电网结构及分压特点,提出了具有代表性的分压线损指标,以河北电网6个地区为例,分析本年度的线损指标状态,与线损理论计算结果相联系,建立各分压指标的影响权重,采用线性综合评价方法得出各地区的评价结果。通过分压指标分析及定性评价,指出各地区的理论线损指标降损方向。

According to the characteristics of power grid structure and partial voltage,a representative line loss indicator of partial volt-age is put forward.Taking six areas of Hebei network as an example,the status of line loss indicator in this year is analyzed,which is in line with results of theoretical line loss Calculation.The weights of each partial voltage index are established.The evaluation results of various regions obtained by linear comprehensive evaluation method.Through the analysis of the partial voltage indicators and the quali-tative evaluation,it points out that the direction of the theoretical line loss reduction for every area.
