In this paper, a doubly fed induction generator (DFIG) wind turbine controller which consists of two control loops is introduced. In steady state, the main control loop ensures that the wind power generators without wind speed measurement can perform active power control tasks below the nominal wind speed while the auxiliary stability control loop restraining the wind power system oscillations by...
A Doubly-Fed Induction (DFIG) wind generator dynamic model is developed in PSCAD. Then a novel active power control strategy based on the indirect speed control is introduced to implement the power control tasks and the limits of these controls are also discussed. The novel strategy ensures that wind power generators without wind speed measurement can achieve the balance control and maximum power...
