摘要
针对配电网中存在着大量的不确定因素对接有双馈风机的配电网节点进行基波和谐波模糊建模。并考虑节点内部存在的关系:在节点基波建模中,考虑并联补偿器和功率因数的关系可以提高理论收敛程度;在节点谐波建模中,考虑风机负荷、无源负荷和非线性负荷的关系可以极大简化模糊谐波建模的复杂程度。最后把双馈风机接入典型33节点辐射型配电网进行模糊谐波潮流计算,证明了所提建模方法使模糊谐波潮流计算的速度和精度都有所提高,通过计算分析了双馈风机发出谐波对配电网的影响。
The fundamental and harmonic fuzzy node models of distribution network with DFIG（Doubly Fed Induction Generator） are presented with the consideration of uncertainty factors in distribution system and the internal constraints of node. During fundamental node modeling,the relation between parallel compensator and power factor is considered to improve the theoretic convergence degree,while during harmonic node modeling,the relation among wind turbine load,passive load and nonlinear load is considered to decrease its complexity. The calculative results of fuzzy harmonic power flow for typical 33-bus distribution network with DFIG prove that,the proposed modeling method improves the calculation speed and accuracy. The impact of the harmonics generated by DFIG on distribution network is analyzed.
