A Yaw Brake is an essential component of the yaw system in a modern horizontal-axis wind turbine. Its primary function is to provide controlled braking and static holding force to govern the orientation of the nacelle—the housing that contains the gearbox, generator, and drivetrain. By precisely managing the nacelle’s position relative to the wind direction, yaw brakes are critical for maximizing energy production, ensuring structural safety, and minimizing mechanical wear.
Core Functions and Operating Principle
Yaw 브레이크 시스템은 yaw 구동 모터와 협력하여 두 가지 중요한 작업을 수행합니다:
Most yaw brakes are designed as active, hydraulically-applied calipers. In this configuration, hydraulic pressure is used to press high-friction brake pads against a large brake disc connected to the turbine tower. Many systems also incorporate a fail-safe, spring-applied mechanism, ensuring that in the event of a hydraulic or power failure, the brake automatically engages, securing the nacelle.
