OPTIMIZING WIND TURBINE OPERATION
SmartWind is transforming wind turbines which use loop control systems as intelligent machines. By receiving real time data from weather agencies and the utilities, they will make smart choices that will optimize production, reduce unprofitable operations, and decrease the stress on the wind turbine components.

BENEFITS FROM VARIABLE SPEED TECHNOLOGY
- Variable speed control offer maximum efficiency and maximum yield, and reduces the stresses on the powertrain..
- Turbulence and wind shear are absorbed as the energy is stored in the mechanical inertia of the turbine.
- Variable speed reduces torque pulsations for increased gearbox life.
- IGBT power inverter induces minimum grid harmonics, reduces torque pulsing and improves the power output quality.

SPECIFICATIONS
