基于统计偏差和技术偏差的低压台区线损率分析方法
摘要：针对低压台区线损率异常原因难以辨析的问题，提出了一种基于统计偏差和技术偏差的线损率分析方法。首先，通过分析统计线损率和理论线损计算模型，结合Matlab数值仿真引入理想线损率的概念。在此基础上，对比分析统计线损率、理论线损率、理想线损率之间的关系得到统计偏差指数及技术偏差指数。再通过比较偏差指数与设定阈值，确定线损率异常原因并制定相应降损措施。最终，通过工程实践验证了该方案可有效辨析线损率异常成因，采取对应降损措施后，试点台区技术偏差指数由1.2降低至1.0，同等供出电量时线损率由3.1%下降至2.5%。
Abstract:To address the issue of identifying the causes of abnormal line loss rates in low-voltage transformer district, a new line loss rate analysis method based on statistical and technical deviations was proposed. Firstly, combined with MATLAB numerical simulation, the ideal line loss rate was introduced by analyzing the statistical line loss rate and theoretical line loss calculation model. On this basis, the relationship among statistical line loss rate, theoretical line loss rate and ideal line loss rate was compared and analyzed to obtain the indexes of statistical and technical deviations. Then by comparing the deviation index with the threshold, the cause of abnormal line loss rate can be determined and corresponding loss reduction measures can be formulated. Finally, engineering practice has confirmed the effectiveness of this scheme in identifying the causes of abnormal line loss rates. After implementing appropriate technical loss reduction measures, the technical deviation index of the transformer district decreased from 1.2 to 1.0, and the line loss rate decreased from 3.1% to 2.5% under the same power supply.
