| Abstract |
This paper presents a sensorless direct power control (DPC) scheme of a doubly fed induction generator (DFIG) applied to a wind generation systems as an alternative to the widely used field oriented control (FOC). The aims of the control system are the control of the power drawn from the wind turbine and the control of the reactive power interchanged between the generator and the grid. DPC is used to control a wound rotor induction generator by means of a rotor connected VSI. The proposed control scheme is based on the direct torque control (DTC) concept, but using active and reactive power as control variables instead of torque and rotor flux. Simulation results show that DPC gives excellent dynamic performance. |
