For wind turbine generators to achieve maximum yields, a trouble-free system status must be guaranteed. Under extreme climatic conditions, however, ice can accumulate on the rotor blades. Falling chunks of ice can cause significant damage. The early detection of ice accretion is important to ensure that the system can be stopped in the event of danger and that the de-icing system can be started.
The ice detection system from Phoenix Contact measures the severity of ice accretion on the rotor blades and ensures that the wind turbine generator operates reliably.
The evaluation algorithm, certified by the DNV GL accreditation company, decides whether to allow operation to continue or to shut down the wind turbine generator.
The sensors, which are simply stuck on, measure the coating thickness of the ice as well as the external temperature on the rotor blade. The sensor is supplied directly with solar power and has a storage capacity of up to 1000 hours.
The sensor signals are transmitted wirelessly to the evaluation unit in the nacelle. Here, the wireless range is up to 250 meters. With an appropriate number of sensors, the system supports the automatic restart function. The evaluation unit is available as a complete control cabinet solution or as a system for integration.
Thanks to the wireless integration of the sensors, the system is suitable both for new wind turbine generators and for retrofitting into existing systems.
Optimize your wind turbine generators with innovative retrofit solutions. Phoenix Contact is the reliable partner by your side to optimize maintenance services on your generators and to sustain the increase of your yields.
