Abstract:

The paper presents the development of a DC motor based Wind Turbine Emulator (WTE) and its performance verification through simulation. The torque signal that represents the actual wind turbine with environmental effect was made to generate at the DC motor shaft. Particularly, the study incorporates the turbine power control strategy including the effect of stochastic and deterministic load components with the shaft dynamics. The WTE with the Wind Energy Conversion System (WECS) is studied to verify the effectiveness of the WTE in the presence of various wind characteristics. The envisaged wind system is based on a DFIG (Doubly fed Induction generator) directly connected to the wind turbine shaft, while the DC output load is supplied by a rectifier and a chopper. The DC load is considered as a resistive load with wide values range. Experimental investigations are provided in partial load regime. The power optimization is performed through power loop in two ways: by controlling the electrical power or by controlling the electromechanical power.
