Control of a cascaded doubly fed induction generator supplying an isolated DC grid

This paper presents the cascaded doubly fed induction generator as a potential candidate machine for electrical power generation in embedded aircraft applications. HVDC network is considered. The machine is connected to a diode bridge rectifier. The set operates as a stand alone DC generator connected to an isolated load. A new decoupled vector control is proposed to regulate the DC bus voltage. The controller aims to retain a constant output voltage regardless load and speed variations.
