| Abstract |
A field-oriented control of a slipring induction generator without speed sensor is introduced. The
principle of the control and practical results of a 2.5 MW-Drive and a 30 kW laboratory set are shown.
At first some basic equations to the slipring induction generator are introduced. The internal rotor
current control loops are presented as well as the higher-level control loops. It is distinguish between
the isolated operation, the mains-coupled operation and the synchronization procedure of the stator
voltage. A model to calculate the flux and one to calculate the speed are incorporated at the paper.
Note, that the using of a speed model is unusual at the present available slipring drives at the
windpower market. The presented figures with results are mostly of the 2.5 MW-Drive, except the two
figures, where it is explicit mentioned. |
