Tower Design Load Verification on a 1-kW Wind Turbine: Preprint

Research output: Contribution to conferencePaper


Wind turbine testing at the National Wind Technology Center (NWTC) has been done to characterize both tower top loads and thrust loads for small wind turbines, which is part of an ongoing effort to model and predict small wind turbine behavior and the resulting stresses imposed on the supporting tower. To these ends, a 1-kW furling wind turbine mounted on a 10-meter tower was instrumented andmonitored via a data acquisition system for nearly a year. This test was conducted to verify the design loads as predicted by the simple design equations provided in the draft revision of the International Electrotechnical Commission (IEC) Small Wind Turbine Safety Standard 61400-02 CDV (hereafter called 'the draft Standard'). Data were captured for several operating conditions covered by thedraft Standard. This paper addresses the collected data and what conclusions can be made from it.
