Abstract: This paper focuses on the importance of wind turbine braking systems and their role in controlling and stopping the rotor during maintenance, emergencies, and extreme weather conditions. It highlights the significance of safe and controlled shutdowns in preventing excessive wear and tear on turbine components, reducing the risk of catastrophic failures, and ensuring the safety of maintenance personnel. The paper will also discuss the main types of braking systems used in wind turbines; Aerodynamic, Electrical and Mechanical braking systems, comparing their advantages and limitations. By examining these systems, the paper aims to provide a comprehensive understanding of their functionality and assist in the selection, implementation, and maintenance of appropriate braking systems for efficient and safe wind turbine operation.

Keywords: Wind Turbine, Braking Systems, Turbine’s Rotor, Emergency Stop.
