Performance Analysis of DFIG Based Standalone 2.2 kW Laboratory Prototype Wind Turbine Emulator

This paper is made for the development of a dc motor based Wind Turbine Emulator (WTE) and to show its perfor-mance verification through simulation. Here the torque signal represents the actual wind turbine with environmental effect to generate the DC motor shaft. Present study incorporates mainly the turbine power control strategy, including stochastic effect and deterministic load components with the shaft dynamics. Here WTE with Wind Energy Conversion System (WECS) is studied to verify its effectiveness in the presence of various wind characteristics. The envisaged wind system is based on a Doubly Fed Induction Generator (DFIG), which is directly connected to the wind turbine shaft, while rectifier and chopper is used to provide the DC output load. Here resistive load is basically the DC load with values in wide range. The experimental investigations are provided in partial load regime and the optimum power is performed through power loop either by controlling the electrical power or by controlling the electro-mechanical power.
