Abstract
Methods and Apparatuses for deicing a wind turbine blade are described herein. In one embodiment, an exemplary process includes detecting an icy condition on a wind turbine blade and causing at least a portion of the wind turbine blade to vibrate, causing the ice built up on the wind turbine blade to break off.
Claims26
A method for deicing wind turbine blades, the method comprising:
- detecting an icy condition on a wind turbine blade;
- and
- causing at least a portion of the wind turbine blade to vibrate to break off ice thereon, in response to the detection of the icy condition.
A wind turbine system, comprising:
- a plurality of blades having one or more vibrators located therein;
- and
- a controller coupled to the plurality of blades to detect an icy condition on at least one of the plurality of blades and to cause, via the one or more vibrators, the at least one of the plurality of blades to vibrate in response to the detection of the icy condition.
A system for deicing wind turbine blades, the system comprising:
- means for detecting an icy condition on a wind turbine blade;
- and
- means for causing at least a portion of the wind turbine blade to vibrate to break off ice thereon, in response to the detection of the icy condition.
