由于10 kV馈线负荷数据多且分散,研究中往往将馈线负荷集中分布在一点进行考虑。通过建立递增、递减、均匀分布3个典型负荷模型,推导出3种模型对合环开关两侧电压的影响,然后通过叠加原理计算出合环电流,并与负荷集中分布在一点的计算结果进行比较。通过对广东某地区4个合环算例进行计算分析,说明在合环电流计算过程中,考虑馈线负荷分布对合环开关两侧电压的影响是十分必要的,可以提高合环电流计算的准确性。
由于10 kV饋線負荷數據多且分散,研究中往往將饋線負荷集中分佈在一點進行攷慮。通過建立遞增、遞減、均勻分佈3箇典型負荷模型,推導齣3種模型對閤環開關兩側電壓的影響,然後通過疊加原理計算齣閤環電流,併與負荷集中分佈在一點的計算結果進行比較。通過對廣東某地區4箇閤環算例進行計算分析,說明在閤環電流計算過程中,攷慮饋線負荷分佈對閤環開關兩側電壓的影響是十分必要的,可以提高閤環電流計算的準確性。

For reason of mass and dispersive data of 1 0 kV feeder load,it often centralizes feeder load on one point for stud-y.By establishing three typical load models including progressive increase load model,progressive decrease load model and u-niformly distributed load model,impact on loop switchgear side voltage by these three models was deduced.Based on super-position principle,loop current was calculated and the calculating result was compared with that of load centralization.By calculation analysis on four loop examples in some area in Guangdong province,it showed that in loop current calculation progress,it was very necessary to consider impact of feeder load distribution on loop switchgear side voltage which was able to improve veracity of calculation on loop current.
