Abstract
This paper proposes a direct power control for doubly fed induction machine for variable speed wind power generation. It provides decoupled regulation of the primary side active and reactive power and is suitable for both electric energy generation and drive applications. In order to control the power flowing between the stator of the doubly fed induction generator and the network, a decoupled control of active and reactive power is synthesised using PI controllers. The obtained simulation results show the feasibility and effectiveness of the suggested method.
Keywords: Doubly fed induction machine, decoupled power control, vector control, active and reactive power, PWM inverter.
