A Vibration Estimation Method for Wind Turbine Blades

摘要: This paper reports the development of a vibration monitoring system for wind turbine blades. is used to estimate deflection at tip blade on tower. Technical accidents blades have become increasingly common. Thus, regular very important prevent breakdowns, especially in cases when begin vibrate excessively. The developed this study satisfies two main objectives practicality. First, our easy install existing turbines. Second, measured real time. Our can be operated using few strain gages attached root, and calculated based monitored stress. direct measurement unnecessary. An estimation algorithm purpose adopted experimental modal analysis. focuses evaluation investigate feasibility system. Basic experiments were conducted simple model 300 W scaled under rotation. Signals from acquired by sensor network sent computer through wireless connection. results show that accuracy acceptably high. Therefore, we conclude proposed practical.
