  • Port purging and deicing system
    Patent number: 8784059
    Abstract: An active sensing system for wind turbines is described. The sensing system may include a plurality of ports, a local sensing device and a load mitigation device and may be operably coupled to a control system. The plurality of ports, local sensing device, and load mitigation device may be operably coupled and configured to monitor air pressure on wind turbine blades, determine if proper sensing operation is occurring, and eradicate an obstruction if proper sensing operation is being prevented by the obstruction. Associated methods performing the sensing and eradication of the obstruction including purging and deicing are disclosed. Wind turbines and wind turbine blades with the active sensing system are also described.
