ASC sensors increase the efficiency of wind turbines

Wind turbines can develop mass-related and aerodynamic imbalances, due to formation of ice or erosion of the rotor blades. The two types of imbalance have different effects on the overall system: While mass-related imbalances primarily cause damage to the wind turbine, aerodynamic imbalances additionally reduce the electricity yield. In a 2 MW system, the average loss of yield due to imbalances costs about 20,000 euros per year**.

Wind turbines can therefore achieve full efficiency only if imbalance measurements are carried out regularly. Capacitive accelerometers from ASC play a key role here, since they optimally measure the vibrations that are critical for wind turbines. The triaxial accelerometers ASC 5511LN and ASC 5515LN offer not only exceptional signal and amplitude resolutions of <20 µg (<0.2 mm/s2), but also operate reliably in the range of rotor frequencies to be evaluated (<0.5 Hz).

Capacitive accelerometers from ASC are helping wind park operators to increase the efficiency of their systems. They therefore play an important role in the energy transition and climate protection.
