Sensors for wind turbines Condition monitoring of wind turbines increases their performance and the service life of components and machines. Modern sensor technologies can help to prevent repairs and to optimize maintenance cycles, not only during the construction and manufacturing of wind turbine components, but also in test benches and in the wind turbine itself. Furthermore, sensors can increase operational safety and minimize failure rates. In particular, sensors from Micro-Epsilon have proven invaluable in various applications with regards to safe operation, especially when it comes to supporting...

Gearbox temperature The gearbox temperature is measured during operation. Heating up of gearbox components may indicate a potential problem with a component. Subsequent remedial action can be started or maintenance planned. Oscillation measurement of the drive train Wind turbulence causes dynamic loads on the structure and the drive train. To measure these oscillations, high-precision and temperature-stable acceleration sensors from MicroEpsilon are used. Oil gap measurement of the shaft Eddy current displacement sensors measure the oil gap, i.e. the distance that is filled with lubricant between...

Rotor gap measurement 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 provide unmatched accuracies. Air flap opening In order to control air supply, the air flaps automatically open and close depending on the temperature. Drawwire displacement sensors monitor the position of the open air flap. Supporting moments of the nacelle In order to monitor the supporting moments, eddy current displacement sensors measure the distance between the nacelle...

Foundation measurements Laser triangulation sensors measure the distance between the tower and the foundation in order to detect the tower movement. High measuring rates enable the sensors to detect any changes reliably. Depending on the number of sensors installed, detailed evaluations about the vibration behavior can be made. 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 10 m due to mechanical loads. Draw-wire sensors...
