Vestas De-Icing System Your benefits at a glance: · Targeted de-icing to maximize power curve recovery · Low risk of lightning damage · Serviceable from the hub and blade root end · Automatic setting triggers only when there is an expected net power production gain after de-icing · Full SCADA integration · No impact on blade profile, noise, or overall turbine performance · Simultaneous de-icing of full rotor set Product Availability: VDS is available for the V112-3.3 MW™ turbine variant. Check with your local Vestas contact for more information. How do you boost your business case in cold climate? Cold climates can often mean icy conditions. Ice build-up on your blades can have a negative impact on your power curve whether you de-ice or not. The Vestas De-icing System (VDS) offers full control and transparency, through a tailored de-icing strategy. VDS is an active de-icing solution consisting of an ice detection system based on your power curve and a hot air flow unit within the blades. The Vestas De-Icing System is fully SCADA integrated. Based on your tailored de-icing strategy, the system can be triggered automatically or manually. Automatic control protects your investment by using a specific algorithm to detect power curve degradation, optimizing the trigger point when the de-icing system is activated. This trigger point is the energy break-even point, where the production loss after de-icing can be regained within a few hours. Under automatic control, the turbine will stop to de-ice only when there is an expected net power production gain after de-icing. Triggering when it matters.

A targeted flow of hot air heats up the outer 1/3 of the blade full chord and outer 2/3 of the leading edge to tip end. 1/3 full chord The Vestas De-Icing System de-ices the full rotor simultaneously, by heating up the blades internally with an efficient flow of hot air. Each blade contains its own de-icing system that work simultaneously to capture, heat and propel air through a specially designed outlet within the blade. Making air work for you. Can you de-ice without compromise? The Vestas De-Icing System is designed for turbine life time, with no impact to overall turbine performance....
