摘要: The converter behavior in harmonic studies or stability analysis can be evaluated by its output impedance. In order to overcome the nonlinearities introduced PLL, linearized models around operating point are typically used. However, case of an imbalance system dq signals not dc anymore, and therefore, linearization cannot done. this paper a Decoupled Double Synchronous Frame PLL is used eliminate oscillations frame signals. small signal model including unbalanced current controller presented paper.
