Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The use of the Doubly-fed Induction Generator (DFIG) in large wind turbines (MW-class) is growing rapidly. In order to investigate the dynamic response of a wind turbine withDFIG connected to the power system during grid disturbance, a model has been developed. This model includes aerodynamics, the mechanical drive train, the induction generator as well as the control parts. The response of the system during grid disturbances is studied. An inclusion of saturation effect in the generator during faults is included as well.

Konferensbidrag (refereegranskat)abstract
- This paper considers minimization, by means of control, of losses in permanent-magnet synchronous motor (PMSM) drives in hybrid-electric vehicle (HEV) applications. A case study is presented to investigate the impact of loss minimization for an experimental PMSM drive, developed for propulsion in a series HEV. The case study shows that the additional inverter losses, due to the extra field weakening added, reduce the potential to minimize losses considerably.

Sensorless control of PMSM drives for hybrid electric vehicles
- 2004

Konferensbidrag (refereegranskat)abstract
- This paper considers the implementation of a speed and position estimator for a permanent-magnet synchronous machine in a hybrid-electric vehicle application. A modified variant of the estimator of phase-locked loop type, previously developed by Harnefors and Nee, is presented, in order to take into account effects of saliency and operation in the whole speed region. Furthermore, design rules for all parameter settings are given. Based on drive-cycle simulations, important operating points are chosen for evaluation, with good results, on an existing experimental setup.
