Power Factor Control of Wound Rotor Inductiion Generator for Wind Power Generation

In wind power generating system connected in power grid the value of stator flux has almost constant because the stator side of wound rotor induction generator is connected to power grid. Using the stator and rotor current it is possible to achieve control of generating power in stator side. This means that we can control the power factor by decoupled rotor current in synchronously rotating reference frame. To verify the theoretical analysis results of computer simulation and experiment are presented to support the discussion.
