应用于双馈感应电机的背靠背变流器直流母线状态被动与在线监测

This article proposes a passive and an online estimator of the dc bus parameters (series resistance $R_s$, inductance $L_s$, and capacitance $C$) used in doubly fed induction machines for wind applications. This kind of machines is widely adopted as generators for wind applications, where predictive maintenance is an important cost-reduction driver. Two implementations are described, plug-in or pa...
