The power retrieved from wind energy systems depends on the power set point traced by maximum power point tracking. The mechanical power from the wind turbine is affected by turbine's Tip Speed Ratio (TSR). It is defined as the ratio of turbine rotor tip speed to the wind speed. At optimal TSR, the maximum wind turbine efficiency occurs for a .

controller is charged to start up the wind turbine in the case of favorable wind and to shut down in the case of high winds. The intermediate level controls the wind turbine components, which includes generator torque, blade pitch control, yaw control and power electronic unit. Wind turbines cannot operate at all wind speeds due to physical .

From the layout of the wind turbine drivetrain shown in Figure2, two main bearings support the main shaft and two torque arms support the gearbox housing. It is, therefore, a four-point suspension wind turbine drivetrain. The geometrical specification of the gears and bearings of the wind turbine drivetrain can be found in the literature [21 .

V A wind turbine blades circular area swept out by turbine blades Fig. 3.1 (a) The mass of air passing through the circular area swept out by the turbine blades each second is 7.5 kg.

The wind turbine consists of a turbine at variable speed with a generator. Under the effect of the wind, the generator turns at speed more important than the wind turbine. It is necessary to adapt this speed by inserting a multiplier of speed, as shown in Fig. 5 [11], [12]. The speed of the wind turbine can be modeled by a scalar
