Wind power plant nacelle

The nacelle of a wind power plant is the heart of the turbine. It contains key components such as the generator, gearbox, and control systems. To increase operational efficiency, automation solutions are increasingly being used to control the alignment of the nacelle and the dynamic adjustment of the rotor blade angle to the current wind conditions. IIoT sensors provide the control systems with the relevant data on the plant status and weather conditions. Perfect interaction between sensor technology, automation, prediction, and evaluation is therefore essential for efficient wind energy generation. It also plays an important role for predictive maintenance. Find out more about our systems and solutions for wind turbine nacelles!

Braking system

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.

Gearbox

3 Solutions

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.

Climate control

Pressure monitoring

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.

Generator

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.
