Abstract: A method of de-icing a wind turbine blade (5) comprises the steps of: generating heated air using heating means (10) provided in the root portion of the blade; and continuously circulating the heated air around the interior of the blade through at least a portion of two more longitudinal blade cavities (24, 26, 28) defined within the blade. The circulating step includes: channeling the heated air from an outlet (32a) of the heating means at least part way through a first longitudinal blade cavity (26), towards the tip end (18) of the blade; at a position along the length of the blade, diverting the heated air from the first longitudinal blade cavity (26) into a second longitudinal blade cavity (24); and channeling the diverted air at least part way through the second longitudinal blade cavity (24) back to an inlet (34) of the heating means (10). The heated air is circulated through at least a central cavity (24) and a leading edge cavity (26) defined between longitudinal webs (22) within the blade.

Abstract: Temperature Control Based on Weather Forecasting Examples are generally directed to techniques for controlling a temperature of a blade, such as a blade in a wind turbine system. One example of the present disclosure is a method of controlling a temperature of a blade. The method includes inputting current weather conditions and future weather conditions into a processor, generating a first power production, generating a second power production curve based on future weather conditions, comparing the first power production curve to the second power production curve, determining which power production curve minimizes a new power production loss of the blade, and adjusting a heating cycle of the blade based on the power production curve that minimizes the net power productions loss of the blade.

Abstract: According to an embodiment, a method of controlling a temperature of a blade includes generating a first power production curve based on current weather conditions and generating a second power production curve based on future weather conditions. The method also includes, in response to determining that the second power production curve reduces a net power production loss of the blade more than the first power production curve, adjusting a heating cycle of the blade based on the second power production curve rather than the first power production curve.
