Abstract:Aiming at the urgent need of solving environmental temperature infuence in the complex impedance icing detection,analyzes the relaxation polarization process of ice, combines the experimental data to obtain the relationship between the complexpermittivity and temperature of ice, and proposes a temperature compensation method for complex impedance icing detection. In orderto improve the accuraey of temperature compensation and reduee the workload of calibration, implements an aceurate and reliabletemperature measurement compensation method through the analysis of the relaxation polarization theory and the construetion of atemperature drift model. It weakens the influenee of icing thickness on temperature compensation, and greatly reduces the complexityof temperature compensation for complex impedance parameters. Icing experiment results show that the proposed method can reducethe influence of temperature drift on the measurement results by more than 80% under ambient temperature of -24℃ to -3℃, whichsignifcantly imprmoves the compensation accuracy and calibration efficieney. The proposed method has certain value of engineeringapplieation.
