OVERVIEW

Design

characteristics

Blades Delta shaped blade tips improve the wind turbine blade performance, similar to wing tips on modern aircraft. 1 Detachable blade tips during transportation reduce the overall blade length, allowing the blade to fit in a standard shipping container, reducing the shipping costs for customers. Fixed Pitch/Yaw Rotor does not require sensors or motors to align the wind turbine with the wind, thus eliminating the need for complex control systems. 2 The rotor can harness the wind from any direction offering superior performance in turbulent and gusty wind conditions. Work Platform
Built in work basket and ladder allow servicing and maintenance to be performed easily and safely. 3
Structure
Tripod tower & screw-pile foundation for increased stability and environmentally friendly, concreate free foundations. 5
Containerised Generation & Control
Majority of major components at ground level, simplifying installation, operation and maintenance. 6 Control system regulates rotor speed during high winds and does not require blade pitch control, simplifying the mechanical control requirements.
Anemometer
Wind speed sensor accurately tracks the behaviour of the wind in real time, in order to improve the turbine’s performance and safety. 4

Reliability & Safety

SAFETY

  • Base Level: Regenerative braking slows the turbine rotor down while still harvesting energy.
  • Second Level: Electronic control system activates mechanical brake.
  • Third Level: Quad pneumatic, fail-safe mechanical brakes deploy, bringing the turbine to rest in as little as 10 seconds.

DATA INPUT &
MANAGEMENT

  • Integrated microprocessor with multiple sensor inputs: wind speed, power, voltages, currents and phase, rpm, vibration and temperature alerts.
  • LCD display in control box. Can output to local PC or be monitored remotely via the internet.
  • Remote Monitoring: Allows remote monitoring of the wind turbine in order for Ryse to ensure the turbine is operating at its peak performance.

CONSTRUCTION &
MAINTENANCE

  • Limited plant requirement for installation.
  • Majority of major components at ground level, simplifying installation, operation and maintenance.
  • Environmentally friendly screw pile foundation instead of a concrete foundation.
  • Screw pile foundation offeres quick relocation and re-deployment.
  • Ryse service contract available.
