Blade heating control for wind farm operators

Linking blade-surface measurements to an existing heater lets wind-farm operators choose heating cycles from the recorded icing condition. EOLOGIX-PING provides the HEAT application using its ON-BLADE arrangement of wireless instruments. The application measures surface temperature and ice thickness, then uses the turbine's control interface for the selected anti-icing or heating response.

Wireless Blade Sensors, or WBS, attach to the outer blade surface. Capacitive elements measure the icing condition, with temperature elements recording the surface temperature. Flexible solar cells and rechargeable energy storage power the blade instruments. A radio link sends their values to a base station in the turbine, with antennas included in the field arrangement. The integrated controller uses those measurements when starting and stopping the installed heating system.

Operators examine the blade condition and heating status through the selected dashboard access. Alerts bring a changing condition to the operating team, and recorded measurements help staff assess the response of the heater. The package includes blade sensors and a base station, with training and support for the deployment. New installations and retrofits use the corresponding turbine-control integration, giving the team a measurement record alongside the resulting heating cycles.
