Abstract
Examples are generally directed to techniques for monitoring and controlling heating elements in wind turbine blades and the wind turbine blades. One example of the present disclosure is a method of monitoring and controlling a condition of a heating element in a wind turbine blade and the wind turbine blade. The method includes measuring a voltage applied to the heating element and measuring the current flowing through the heating element. The method further includes calculating a resistance of the heating element using the measured voltage and the measured current and storing the resistance in a database. The method further includes determining whether an event corresponding to a failure of the wind turbine blade or the heating element in the wind turbine blade has occurred. When the event occurs, control of the heating element is adjusted.
