Press Release: Our dutch partner Topwind is delivering the light:guard Aircraft Detection Lighting System for Windplan Groen

Topwind and Windkoepel Groen have reached an agreement for the supply of ADLS for all parks within Windplan Groen. ADLS stands for Aircraft Detection Lighting System, an advanced system that allows aviation lighting on the wind turbines to be turned off as much as possible at night and in the evening. The system’s delivery is in close collaboration with Topwind’s partner Light:Guard, a party with extensive experience in this field in neighboring country Germany.

Multilateration
The system provided by Topwind and Light:Guard is based on transponder technology. Aircrafts emit a transponder signal, which is then received by receivers on the wind turbines. Unique to the approach at Windplan Groen is the additional use of multilateration (MLAT), a refinement technique that allows for even more precise determination of the aircraft’s position, resulting in further “lights-off time.” Given the proximity to Lelystad airport, this holds extra value for humans and the environment.

Technical Feat
Once this system is operational, it will become the largest Dutch wind project using ADLS technology based on MLAT. The substantial mast heights (around 160m) will significantly contribute to the system’s ‘detection range.’ Optimal signal strength and coverage are expected in the flat Flevopolder. Additionally, the wind plan comprises various types of wind turbines. Martin van den Bosch, project leader from Topwind, stated, “It’s fantastic to be able to integrate all three different turbine types with our interface. The combined IT expertise of Topwind and technology partner Light:Guard, along with a high dose of practical experience, enables us to manage this integration optimally.”

Outlook
Before the system becomes operational, a test phase will take place, including a practical flight test. The delivery of the ADLS system aligns perfectly with Topwind Systems’ mission to support wind park operators with innovative systems. Topwind is actively engaged in further deploying ADLS across the country.
