Optimum Configuration of a Small-/Medium-Scale Wind Turbine Towers based on its Dynamic Characteristics

摘要

While the recent activities to introduce wind power generation systems are getting popular, the accidents caused by the vibration are reported to be increasing especially for the small-or medium-scale wind turbine towers. In this paper, stepped cylindrical mono-pole towers and wire supported straight mono-pole tower typical for the horizontal axis small-/medium-scale wind turbine systems are selected to study their optimal shapes and configurations.
