Decoupled Power Control For Doubly-fed Induction Generator Using Sliding-mode Control [rozsprze{ogonek}żone Sterowanie Moca{ogonek} W Generatorze Dfig Przy Wykorzystaniu Metody ślizgowej]

This paper proposes a decoupled control of active and reactive power for doubly-fed induction generators (DFIG) through the rotor currents using sliding mode control (SMC). In order to decouple the active and reactive power generated, stator-flux-oriented vector control is applied. The sliding mode control strategy proposes is based on two sliding modes plus PI controllers whose main advantage is the easy implementation. Simulation and experimental results are presented to validate the proposed control scheme for a 2 kW DFIG during stator active and reactive power steps and speed variation. During transient operation it is checked good dynamic response.898100105Abad, G., López, J., Rodríguez, M., Marroyo, L., Rodríguez, M., Iwanski, G., (2011) Doubly Fed Induction Machine: Modeling and Control for Wind Energy Generation Applications, pp. 414-421. , John Wiley & SonsBaroudi, J.A., Dinavahi, V., Knight, A.M., (2007) A review of power converter topologies for wind generators, 32, pp. 2369-2385. , Renewable EnergyNetto, A.J., Barros, P.R., Jacobina, C.B., Lima, A.M.N., da Silva, E.R.C., Indirect field-oriented control of an induction motor by using closed-loop identification (2005) Industry Applications Conference, 2, pp. 1357-1362. , 2005.
