High-Order Models of Doubly-Fed Induction Generators
Vattenfall Research and Development, Department of Power Technology, Sweden .
2005 (English)In: Wind Power in Power Systems, John Wiley & Sons, 2005, 587-602 p.Chapter in book (Other academic)
Abstract [en]

The chapter focuses on the modelling of Doubly-Fed Induction Generators (DFIGs). The chapter presents a model of a doubly-fed induction generator on the most detailed level namely a 6th-order state variable model including both rotor and stator electromagnetic transients. The Voltage Source Converter (VSC) of the rotor is not modelled with a detailed modulation scheme, rather it is assumed that the switching frequency is infinite. In spite of the later simplification, limitations in the voltage generation by the converter due to the dc-link are taken into account and are implemented as limitations to the voltage and torque controllers. The chapter describes a Sequencer with different modes of operation of the DFIG. The DFIG-model is tested in a small power system simulated within instantaneous value mode. No verifications have been made to a real installation of a DFIG-model.
