Abstract: A control system for controlling an operation of a resistive heater includes a dielectric parameter determination module, a prediction module, and a heater operation control module. The dielectric parameter determination module determines a material property of a dielectric material of the resistive heater when the resistive heater is in an active mode. The prediction module predicts a life expectancy of the resistive heater based on the material property of the dielectric material. The heater operation control module changes operation of the resistive heater based on the material property and the life expectancy.

Abstract: Models for predicting ice formation and/or accumulation on wind turbine blades and methods of their use in optimizing performance of wind turbines in the presence of adverse local weather conditions are disclosed. In certain embodiments, the predictive models include historical data of local meteorological conditions including, inter alia, wind speed, temperature, and relative humidity conditions and are useful, inter alia, for preemptively managing performance of wind turbines operation/shutdown cycles in response to a future predicted blade icing event based on a model of the present invention.
