In cold and humid climate conditions, the surface of wind turbine blades is prone to icing. Effective de-icing methods have attracted widespread attention from scholars around world. this study, an external hot-air test system was designed constructed. A program for FRP plate formulated. The main parameters experiment included temperature (25~55 °C), speed (7~13 m/s), jet distance between outlet pipe ice (100~400 mm), inner diameter device air (50 mm, 63 90 different times. Critical data on mass, energy consumption, efficiency were obtained. experimental results showed that method could be used de-icing. Under conditions experiment, lowest consumption highest 21.1 kJ/g 4.95% achieved when 55 °C 13 m/s.

In areas where there is high humidity and freezing rain, a tendency of blade icing on wind turbines. It results in energy dissipation mechanical abrasion also creates safety concern due to the risk having falling ice. Real-time online detection crucial enhancement power generation efficiency The current methods that use ultrasound, optics, vibration, electromagnetics are already studied. But these have their drawbacks, including small ranges, low accuracy, large size, challenges distributed installation, making it hard capture real-time dynamics de-icing processes turbine blades. To this end, paper presents new surface technique using microstrip lines. This approach uses impact state thickness effective dielectric constant line surface. analysis time-domain features microwave signals, which facilitates identification both corresponding thickness. Simulation experimental measurement linear S-shaped sensors used research order compare response variation layer. seen for ranging from 0 mm 6 mm, imaginary part S21 parameter has more significant change than line. above experiments confirm phase shift value always higher same thickness, proves sensitive one. Also, was possible establish relationship between values makes predict developed technology intended usage similar areas. method saves size sensors, conduct measurements at various points. especially beneficial blades can be further applied aerospace, automotive, construction, bridges.
