Pressure monitoring
In addition to the pitch-control system in the rotor blades, a wind power plant has a pressure-monitored mechanical brake between the gearbox and the generator, which quickly stops the turbine in an emergency or during maintenance work. This disk brake works similarly to a car's brake. It is activated when the aerodynamic brake alone is not sufficient to stop the plant safely.

The wind turbine gearbox increases the slow rotation of the rotor blades to the required generator speed, thereby connecting the low-speed shaft of the rotors to the high-speed shaft of the generator to efficiently convert the wind energy into current. The resulting stresses on the gearbox tooth flanks are made manageable by the use of sophisticated lubrication technology.

The climate control of a wind turbine nacelle ensures optimal operating conditions for sensitive technical components such as the generator, the gearbox, and the electronic components ─ even in bad weather. This helps to prevent standstill times, extends the operating life of components, and maintains the efficiency of the plants.
2 Solutions
The generator of a wind power plant converts the mechanical energy of the rotors into electrical energy through electromagnetic induction. In gearless systems, it is directly connected to the rotor so that the electrical components are subject to stronger speed fluctuations in strong winds. To prevent overheating, the inside temperature must be constantly monitored.
