摘要
分析了规则风电场和不规则风电场布局的基本规则,建立了双馈型风电机组和永磁直驱型风电机组单机小信号模型。采用特征值分析法,分别研究了由这两种机型构成风电场的同机型风电场和混合机型风电场的机网相互作用。结果表明,两种不同机型构成的同机型风电场的机网相互作用有着明显的差异,并且相比同机型风电场,混合机型风电场的机网相互作用也有显著的变化。
Basic layout rules for regular and irregular wind farms were analyzed. Single unit small-signal models were established for doubly fed wind generation set and permanent magnet direct drive generation set. Interaction between farm generator and grid for the wind farm using same type of generators and the wind farm using mixed types of generators was studied respectively. The results showed that there existed a significant difference in interaction between wind farms using same type generators,and wind farms using mixed types of generators had a significantly different interaction than that of those farms using same type generators.
