An optimal speed wind turbine test bench system for PMSG machines with MPP control

An accurate test bench system is required in the research, design and development of Wind Energy Conversion Systems (WECS). Scaled laboratory prototypes are necessary to replicate the characteristics of a wind turbine for any wind speed in a controlled test environment without depending on natural wind resources and actual wind turbine. Optimal Speed Maximum Power Point (MPP) algorithm is embedded into the test bench system to maximize the efficiency of the overall system. Effects of 3p torque oscillation on the wind turbine are studied. The simulations were carried out in MATLAB/SIMULINK and test bench system is prototyped using a TI DSP F28035.
