摘　　要：在电力系统中,线损是电能损耗比较常见的一种能量损失,因此,分析配电网线损产生的原因,并对其进行理论计算,对降低能耗显得尤为重要。分析了线损产生的基本原因,同时对计算线损的常用方法进行简单分析。在诸多方法中,针对等值电阻法具有适用于运行中配电网电能耗损计算的特点,对等值电阻法的原理,应用条件等进行分析,将等值电阻法应用于10 kV配电线路的线损计算中。利用算例结果和实际对比,从实用性角度出发,分析该方法在实际中的应用性。结果表明,等值电阻法误差较小,其结果对建立线损的评估指标具有一定的参考意义。In power system, line loss is a common energy loss of electric energy loss. Therefore, it is particularly important to analyze the causes of line loss in distribution network and carry out theoretical calculation to reduce energy consumption. This paper introduces the basic causes of line loss and simply analyzes the common methods of calculating line loss. In many methods, in view of the equivalent resistance method is suitable for the operation of the distribution network electric energy loss calculation characteristics, the principle of equivalent resistance method, application conditions are analyzed, the equivalent resistance method is applied in the 10 kV distribution line loss calculation. Based on the comparison between the result of calculation example and practice, the application of this method in practice is analyzed. The results show that the error of equivalent resistance method is small, and the results have a certain reference significance to establish the evaluation index of line loss.
