文章结合上海市低压电网实际情况,试图寻找一种所需数据少,计算速度快,准确度高的线损计算方法。在前推回代法的基础上,从算法本身、考虑三相不平衡影响以及功率因数三个方面,改进现有算法,并运用于台区实例计算,对比算法性能,得出结论。
文章結閤上海市低壓電網實際情況,試圖尋找一種所需數據少,計算速度快,準確度高的線損計算方法。在前推迴代法的基礎上,從算法本身、攷慮三相不平衡影響以及功率因數三箇方麵,改進現有算法,併運用于檯區實例計算,對比算法性能,得齣結論。

In combination with the actual situation of Shanghai distribution network, this article tries to ifnd an easy, fast and accurate method of line loss calculation. The existing back/forward sweep method in three aspects were improved: the algorithm, three-phase imbalance charge and power factor. Then the modiifed method was used to calculate the line loss of several distribution network as example. The results of different methods were compared and a conclusion was got.
