摘要
讨论了三相配电网络中变压器、线路、负荷的模型 ,尤其考虑了变压器接线方式、移相作用和非标准变比对三相潮流的影响 ,推导了变压器两侧相应的相电压、相电流关系 ,针对辐射型配电网络的特点 ,提出一种基于支路电流前推回代的 ABC相分量潮流算法 ,算例表明该算法非常有效。
The m odels of the transform er,feeder and load in the three- phase distribution system were discussed in detail. Particularly the transformer winding connection,the phase shifting between prim ary and secondary windings and the tapping of the transformer with non- standard transformation ratio are considered.And the corresponding phase voltage formula and phase current form ulas of transformers are deduced.In accordance with the characteristics of the radial distribution system s, A three- phase back/forward sweep load flow algorithm based on ABC phase- components is proposed. The efficiency of the proposed method is proved on the test network.
