This paper presents a stand-alone doubly wound asynchronous generator (DWAG) employed for feeding single-phase loads with harmonic compensation. Pulsewidth modulation controlled back-to-back-connected voltage-source converters (VSCs) are used with a battery-supported common dc link. The stator converter (SC) with a star-delta-connected transformer is used to provide functions of a load leveler, a...
This paper presents the experimental implementation of a Doubly Fed Induction Generator (DFIG) for variable speed Wind Energy Conversion Systems (WECS) for improving the voltage profile at a remote location. Voltage control is becoming more challenging due to increase in wind energy penetration. This voltage control problem is addressed by controlling both the voltage source converters (VSCs) of DFIG...
This paper deals with the modeling and control of a three phase four wire autonomous Wind Energy Conversion System (AWECS) using Doubly Fed Induction Generator (DFIG) feeding local loads. It presents a procedure for design and selection of the components and a vector control algorithm for AWECS. The proposed control algorithm for AWECS is realized using back to back connected Pulse Width Modulated...
