Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics and provide an opportunity for delegates to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please, join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO014: Rotor rotational speed detection and rotor overspeed using TripleCMAS
Xavier Tolron, Head of Analysis and Drone R&D, Ventus Engineering GmbH
Abstract
The rotational speed of a Wind Turbine Generator's rotor must be monitored at all time. The rotational overspeed for turbines can be devastating on many levels such as: the failure of the turbine's shaft, blade unbalance, gear teeth damage, and wear of the mechanical components inside the nacelle. The Critical Components Condition Monitoring, fault detection and instant Alarm System (TripleCMAS) technology provides information based on data collected by 3-axis accelerometer sensors located inside the rotor. Three accelerometers are installed inside of the individual wind turbine blades identically. Each sensor is placed the same distance from the centre of rotation, with one sensor-axis aligned along the length of the blade, one sensor-axis aligned with the blade-flapwise axis, and the last sensor-axis aligned with the blade-edgewise axis. This alarm system can determine at all time whether the turbine is in operation or not and the rotational speed of the rotor. An acceptable rotational speed threshold will be determined to fit the turbines' feature and will be compared against the current operating rotational speed.
