Experimental evaluation of wind turbines maximum power point tracking controllers

摘要: Wind energy technology has experienced important improvements this last decade. The transition from fixed speed to variable wind turbines been a significant element of these improvements. It allowed adapting the turbine rotational variations with aim optimizing aerodynamic efficiency. A classic controller that slow dynamics relative mechanical drive train is implemented in commercial turbines. objective work related paper evaluate implementation, on test bench, whose can be adjusted faster and compare particular its efficiency conventional controller. In theory, higher non-classic lead better 180 kW simulation model validated field data emulated an 18 bench. emulator also validated. Test bench trials are very useful step between numerical real system because they allow analyzing some phenomena may not appear simulations without endangering system. show non-conventional leads offset by torque electric power fluctuations. Nevertheless, amplitudes fluctuations relatively low compared their rated values.
