This paper examines an intelligent operational method to extract more power out of 1.1 kW wind turbine (WT) permanent magnet synchronous generator (PMSG) by exploiting untapped thermal potential margins. To implement this, unified multi-physical electromagnetic and thermal models of wind turbine generator are required. These were developed in different commercial software. The integrated model also consists of a new integration of pitch and field-weakening controllers that allows controlled overload operations in the constant power region by increasing generator speed and maintaining the generator terminal voltage at rated condition while increasing current magnitude, without interfering with operation in the maximum power point tracking (MPPT) region. The proposed model is tested with both fixed wind speed and a field measured wind speed profile. The simulation results show extra WT generator energy harvesting while the generator is not thermally overloaded.
