Reducing Wear on Wind Turbines
Deutsche Windtechnik has been measuring wind turbine rotor blades using a laser-based blade angle procedure since 2015. The company has discovered serious shortcomings on some of the 273 Vestas turbines examined to date. Where the relative blade angle deviations were 0.5 of a degree or more, the service technicians corrected the settings. This makes the wind turbines run more quietly, ensures less strain on the material and reduces wear.

Deutsche Windtechnik is to carry out measurements on all the wind turbines it maintains as part of a full maintenance contract that includes large components. This year the service provider will be checking the Vestas, NEG Micon and Siemens wind turbines. Similar examination of offshore wind turbines will follow.
