Active Reeling System

Definition

An active reeling system is a mechanism used in tethered airborne wind energy systems to control the extension and retraction of the tether by actively managing its tension and position. This system allows for efficient energy capture by adjusting the tether length based on wind conditions and the operational state of the energy-generating unit, leading to optimized performance. The active control provides a dynamic response to environmental changes, enabling the system to maximize energy generation while minimizing wear and tear on components.
