Noise reduction in wind turbines

Wind turbines generate environmentally friendly power, but are often rather unpopular with their residents in the neighborhood, as they also generate noise. One of the noise sources in wind turbines is ...

Oscillation measurement of the drive train in wind turbines

Oscillation of the drive train (rotor imbalance, overloading) exceeding the limit values may lead to a failure of components and plant parts. Prerequisite for early recognition of damage and for predictive ...

Measuring the bearing gap in wind turbines

To date, bearing gaps were measured during standstill based on a tactile principle. Therefore, long inspection intervals were required, which in turn, may increase the risk of a complete plant failure. ...

Rotor stress tests in the test bench

Test rigs have been developed for load tests on wind turbine rotor blades and simulate the real loads caused by high winds and weather. The tip of the rotor blade can be distorted by up to 10m due to mechanical ...

Rotor gap measurement in the generator

In order to monitor rotor behavior in the generator, capacitive displacement sensors measure the gap between stator and rotor. Despite high temperatures and electromagnetic fields, capacitive sensors from ...

Monitoring the air flap openings

In order to control air supply, the air flaps automatically open and close depending on the temperature. Draw-wire displacement sensors monitor the position of the open air flap.

Alignment of solar panels

Aligning solar panels in relation to the course of the sun increases the energy yield, and therefore the plant effectiveness. Inclination sensors ensure that the panels are always properly aligned.

Monitoring the tower oscillation

Wind turbines are exposed to oscillations and shock loads. In order to avoid damage and expensive downtime, these tower oscillations are monitored. When exceeding limit values, the plant is reliably shut ...

Supporting moments of the nacelle

In order to monitor the supporting moments, eddy current displacement sensors measure the distance between the nacelle and the tower, which enables early recognition of any oscillations. Therefore, the ...

Measuring the foundation movement

Laser triangulation sensors measure the distance from the foundation in order to detect the tower movements. High measuring rates enable to detect vibrations directly. Depending on the number of sensors ...

Measuring the deflection of the clutch disc

Eddy current displacement sensors measure the axial, radial or tangential deflection of the clutch disc. These robust sensors are designed for harsh ambient conditions and, due to their extremely compact ...

Measuring the temperature of frictional heat on bearings

The gearbox temperature in wind turbines is measured continuously during operation. Heating up of components may indicate a potential problem with a component. If a certain threshold is exceeded, subsequent ...

Oil gap measurement in shafts

With regard to predictive maintenance, the oil gap should be measured, i.e. the distance between the bearing surface and the shaft filled with lubricants. Despite pressure, high temperatures and lubricants, ...
