Efficiency Optimization in Medium Power Wind Turbines: an Innovative Mechanical Pitch Control System

The paper illustrates the design of a new mechanical system for propeller blades pitch calibration in medium power wind turbines. peculiarity this is its capacity adjusting through feedback control system, which allows turbine to capture maximum amount energy from wind. In work an axial drive was studied by means racks capable linearly all intrinsically synchronous way, with advantage over traditional methods calibration. For different speeds adjusts angle incidence order reduce rotation speed and keep as close possible pre-established conditions generating high efficiency. manuscript examines main analyses simulations conducted during phase. These show that proposed method reach higher efficiencies greater intrinsic stability compared mechanisms experimental results on first prototypes confirm efficiency increase.
