Wind Turbines / 風力發電機

Wind power is a sustainable power source that exploded a few decades ago. Permanent monitoring helps to avoid any unscheduled malfunction. In the worst case, a lack of maintenance could conduct to the turbine shut down or even destruction, cutting off the power production.

There are two types of applications:
•    Turbine monitoring: measurements of vibrations on critical components
•    Tower tilt inclination: angle calculation for proper tower positioning

Explanation of the System

A wind turbine has a simple mechanism: three blades rotate about an axis at low frequencies (typically from 0 to 20 rpm). After speed amplification, the shaft is connected to a generator that converts inertial to electrical energy. The sensors are embedded in a bi-axial or tri-axial container, fixed to a structure to measure its acceleration. A vibration is easily detected due to a different frequency.

Environment Analysis

The sensors will be exposed to a temperature is between -40 and 55°C, with atmospheric pressure. Humidity level can vary from 3% to 100%, whether the wind turbine is working under dry or humid conditions.
Good vibration analysis requires both a broad bandwidth and an excellent precision. The range of the bandwidth allows to notice low or high frequencies, and the precision describes how quickly defect is detected

Critical Technical Properties

Colibrys’ solutions

•    The VS1000 is adapted for vibration analysis: its usual range would be ±2g for blade and structural diagnosis, and around ±10g for internal monitoring. The vibration sensor family offers the best performance for monitoring, with bandwidth from DC 0 Hz to 7000 Hz at -3 dB, and a functioning temperature range from -55°C to +125°C.

•    The TS9000 series is ideal for tilt applications: the TS9001.D largely respects the requirements for tower inclination, reaching a resolution of 0.003°.
