The new, innovative iRotor technology, which uses wireless sensor technology to measure blade geometry changes, is now fully installed and ready for full-scale tests at The Danish National Test Centre for Large Wind Turbines at Østerild. (Photo courtesy of LM WInd Power.
“The complete iRotor solution is now ready for full-scale testing in Østerild. KK Wind Solutions has installed the electrical components of the iRotor solution and the infrastructure, enabling us to collect data. We now look forward to start testing and verifying the solution together with LM Wind Power and Envision,” says René Balle, Chief Technology Officer at KK Wind Solutions.
The project is a joint effort between LM Wind Power, KK Wind Solutions, PolyTech and University of Aalborg and has been partly funded by Innovation Fund Denmark. Envision has agreed to test the technology on their turbine at Østerild in Denmark.
“This project is an example of a successful and close collaboration on technology innovation between leading companies in the wind industry supply chain, research institutions and Innovation Fund Denmark,” says Project Manager Claus Byskov, LM Wind Power.
The research project has a total budget of DKK 65 million of which DKK 33 million is funded by Innovation Fund Denmark. The project was launched in June 2013 and is scheduled to run for three and a half years.
“Everybody in the industry aims at lowering the cost of wind energy and through this joint effort we prove that by combining different fields of expertise we can break technological boundaries which would not be feasible financially or technologically as individual players,” says René Balle.
iRotor is a technology project aiming at developing an innovative technological solution that addresses a key challenge and trend in the wind industry. With the move to lower wind class sites, the need for turbines with longer, lighter blades and lower loads is increasingly required to achieve an attractive cost of energy. The iRotor project aims to develop wireless sensor technology based on radio technology, which measures blade geometry changes on wind turbines in operation, thereby enabling advanced control of the turbine for load mitigation. This will allow developers to install more powerful turbines with longer blades without incurring the excessive additional cost it requires for strengthening the turbine structure. In essence, the technology will extend what can be achieved using blade existing design, material and process technology.
