摘要: A new application of utilizing ultra-wideband (UWB) technology to sense wind turbine blade deflections is introduced in this paper for energy cost reduction. The lower UWB band 3.1–5.3 GHz applied. On each blade, there will be one deflection sensing system, which consists two antennas at the root and antenna tip. detailed topology challenges system are addressed. Due complexity problem, first realize on-blade radio link simplest case, where tip situated outside (and on surface of) a To investigate full-blade time-domain measurements designed conducted under different deflections. measurement setups results provided. If locations properly selected, pulse always sufficient quality accurate estimations measured reveal that tip-root distance can accurately estimated complicated lossy wireless channels around blade. Some future research topics listed finally.
