弱电网下双馈风力发电系统的高频谐振阻尼研究

When operating in a micro or weak grid which has a relatively large network impedance, the doubly fed induction generator (DFIG)-based wind power generation system is prone to suffer high-frequency resonance due to the impedance interaction between the DFIG system and the parallel compensated network (series RL + shunt C). In order to improve the performance of the DFIG system as well as other uni...
