摘要
随着电力系统中谐波的日益增多 ,单相谐波潮流计算已不能满足要求。详细讨论了三相配电网络中谐波情况下的发电机、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不对称谐波潮流的影响 ,推导了变压器两侧相应的相电压、相电流关系 ,并针对在传统谐波潮流算法中考虑了变压器三相模型后有可能不收敛的问题 ,提出了一种基于支路电流前推回代的相分量谐波潮流算法。算例计算表明该算法是非常有效的。
With the increasement of the harmonic quantity in power system ,single phase harmonic power flow calculation can't meet the needs. This paper discusses the components model in detail under harmonic condition in three phase distribution power system, include generator,transformer,line and load. Particularly, the transformer model considers the winding connection, the phase shifting among primary and secondary windings, and the off-normal tapping.The three-phase model of transformer, used in traditional harmonic power flow, may the preuent the model from converging, so the paper proposes a three phase back forward sweep harmonic load flow algorithm based on phase-components. At last, a test example was used to prove the algorithm. The results indicate that the proposed method is efficient.
