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: Explanation of the SystemA 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. Critical Technical PropertiesColibrys’ 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°. |
