We saw previously how obtaining electricity thanks to the wind turbine but it can be efficient if only we can adjust parameters.

Find in the kinematical diagram below the two parameters and indicate the device which is responsible for this:

## How to tune the behaviour of the wind turbine

## Exploring the inside closely

We will now look at the solutions provided by manufacturers to answer this matter. Open the video called REXROTH_DRIVE_AND_CONTROL_TECHNOLOGY_FOR_WIND_TURBINE

Listen closely to the video and fill in the blanks (one word equal one line)

[0’14’’] Within a few years the __________ ______________ has developed into a global industry which is experiencing significant growth rates. Modern wind turbines generate electricity _____________ and _______________ thanks among other factors to innovative drives and control technology. BOSCH REXROTH, one of the world leading suppliers of drive control and motion solutions offers hydraulic and technology systems making a strong partner for wind turbine ________________. High precision MOBILEX GFB __________ drives insure accurate orientation with the wind and turn the nacelle slowly into the wind when the current in wind speed is reached. The compact gear drives consist each of multistage planetary gearbox and output pinion and an electric motor. These planetary gearboxes provide high gear ____________ that enable very centred rotational movements. For rotor blades adjustment REXROTH offer both __________________ pitch drives, which are space savingly mounted inside the ___________, consist each of two or three stages MOBILEX GFB compact and output pinion and a maintenance free asynchronous motor. Drive controllers which have been developed specifically for pitch systems and redundant safety systems guarantee ________________ rotor operation. Alternating rotor blade control and monitoring functions ________________ continuous operation so that the wind turbine generates electricity reliably over the entire operating range. [1’59’’]

[2’34’’] REDULUS GPV gearboxes convert the _________ ____________ ___________ into the ___________

______________ speed up to the _______________. For wind turbine with capacities up to 2 _____________

REXROTH supplies compact gearboxes. They combine a planetary gear stage with 2 ___________ ____________

stages. [2’55’’]

[3’23’’] The yaw and powertrain _____________ functions are _____________ by the very compact brake power unit and optimize brake control system protects the brake power unit from unnecessary wear. [3’38’’]
