Modelling and output power optimisation of a wind turbine driven double output induction generator

摘要: In the paper, a double output induction generator (DOIG) driven by wind turbine is studied. The reference frame model of system including fully controlled rectifier on rotor side derived. Based this model, steady-state equations are obtained in terms stator and currents, voltage slip. These solved both with that DC motor driving DOIG. results compared experimental ones. Finally, an optimisation problem formulated to investigate conditions transferring maximum power from grid system, it shown using DOIG either subsynchronous or supersynchronous modes, possible transfer network wide range speeds without exceeding ratings generator.
