VestasAviation lights activate when needed: One Vestas InteliLight® radar may cover several wind parks*, yet the system only activates lights in the relevant parks. In this case, aviation lights are activated in the blue and purple wind parks, but remain off in the orange wind park. Siting In the case of Vestas wind park planning, the Vestas InteliLight® application is considered in the regular Vestas turbine siting process. For existing Vestas, non-Vestas and multibrand wind park application, a coverage assessment is prepared by dedicated InteliLight® personnel. Specialised siting tools using topographical 3D maps are applied to ensure safe and efficient radar terrain coverage and aviation safety. Installation The compact Vestas InteliLight® hardware is installed on the side of the turbine tower or on a stand-alone mast. Vestas ensures valid type certification and aids in the site preparation and permit application to authorities, including initial application as well as verification and as-built documentation. Availability of Vestas InteliLight®: Vestas InteliLight ® installed on the turbine tower is authority-approved for use in the following countries*: • Germany (Certified by DFS/BMVI) • United States (Certified by Federal Aviation Administration) Other countries can be requested but certification from aviation authority is required Operation Vestas InteliLight® is a complete end-to-end solution, from aircraft detection to controlled activation of aviation light and surveillance hereof. The system continuously and autonomously scans the wind park’s surrounding area. Each radar has an instrumented range up to 36 kilometers. If an approaching aircraft is detected, its distance, speed, and heading are tracked and an automatic assessment is made on whether or not to activate the aviation lights. Optionally, a secondary audio alarm can be triggered through the VHF aviation channels. Service Vestas offers a comprehensive service package that ensures the proper maintenance and operations of the system during the lifetime of your wind power plant. Frequent testing and ongoing reporting by Vestas, coupled with periodic inspection and calibration performed by certified Vestas InteliLight® technicians, enables you to demonstrate that the system is fully functional at all times. * Configuration is country and site dependent, subject to regulation and site conditions. ** Availability on request, depending on turbine type.
