双馈感应发电机适用于速度范围有限的系统，因为可以通过分数额定转换器进行总体控制。然而，这些发电机中使用的电刷和滑环降低了系统的可靠性，并需要更多的维护。双定子绕组感应发电机（DSWIG）是无刷的，消除了这一限制。定子内嵌有两个分布式绕组，转子为鼠笼式。其中一个绕组连接到不可控整流器，另一个连接到分数额定PWM转换器。不可控整流器降低了发电系统内的电能质量。同时，感应发电机中的无功功率需求随着负载而增加。本文论述了一个独立的直流系统的设计和控制的DSWIG的基础上，无源调谐滤波器和串联电容器的组合，用于解决电压调节和电能质量问题。使用MATLAB/Simulink的仿真结果和实验结果（从实验室原型获得）已提交，比较，并讨论了所提出的替代方案的有效性。
Doubly fed induction generators are suitable for systems having limited speed range as the overall control can be carried out by fractionally rated converters. However, brushes and slip-rings used in these generators reduce system reliability and demand greater maintenance. Dual stator winding induction generator (DSWIG), being brushless, removes this limitation. Two distributed windings are embedded in the stator and the rotor is squirrel-cage. One of the windings is interfaced to an uncontrolled rectifier and the other to a fractionally rated PWM converter. Uncontrolled rectifier degrades the power quality within the generation system. At the same time, reactive power demand in induction generators increases with loading. This paper deals with design and control of a standalone dc system based on DSWIG, where a combination of passive tuned filter and series capacitor is utilized to address the voltage regulation and power quality issue. Simulation results using MATLAB/Simulink and experimental results (obtained from a laboratory prototype) have been presented, compared, and discussed to demonstrate the effectiveness of the proposed alternative.
