The implementation of wireless technology using the 802.11s standard and mesh network technology will revolutionise wind turbine and wind park control systems. The increased signal fidelity and packet routing central to this technology will allow more WiFi-enabled sensor networks to be implemented on wind turbine blades. Previous attempts at fully instrumented blade monitoring using optical fibre sensors were expensive and limited in fidelity due to reliability issues. While the subject of WiFi use in pitch control, SCADA and content management systems (CMS), and other communication uses in wind turbines has been discussed for many years, some of the same constraints related to bandwidth and system reliability in the face of lightning strikes and 20-year design life have thus far precluded commercial use.
