Ice detection method and system for wind turbines, using sun radiation sensors
摘要
The present invention defines a system and method aiming at measuring the direct solar radiation received by a wind turbine generator in order to detect ice formation. The measured value is subsequently compared to a theoretical radiation curve wherein measured values on a cloudy day will be well below theoretical curves. Ice detection is made considering the presence of clouds and temperature. Measured parameters are preferably the direct sun radiation transmittance and ambient temperature.
