Class NK Certified | Japanese 9.7 kW Small Wind Turbine

OVERVIEW

Design

characteristics

Blades

Single piece glass fibre blade maximises strength and minimises connection interfaces, limiting points of potential failure.

Swept Area

Superior performance in moderate wind speeds due to the large swept area of 133 m2 maximises power output.

Generator

Induction generator produces 3 phase, sinusoidal output without the need for power electronics, simplifying the control system and increasing the reliability of the system.

Gearbox

Fixed ratio gearbox with a constant rotor speed ensures a low-level noise profile is maintained even during high wind speeds.

Controller & Monitoring

Remote monitoring allows service engineers to assess the status and health of the wind turbine ensuring the system is operating at peak performance at all times.

Work Basket

Built in work basket and ladder allow servicing and maintenance to be performed easily and safely, at a reduced cost, without the need for specialist lifting equipment.

Anemometer

Wind speed sensor accurately tracks the behaviour of the wind in real time, in order to improve the turbine’s performance and safety.

Reliability & Safety

SAFETY

Base Level: Passive stall of blades limits power output.
Second Level: Electronic control system activates mechanical brake.
Third Level: Passive centrifugally activated aerodynamic brakes, concealed in the rotor tips, release, spoiling the rotor aerodynamics and subsequently its ability to rotate.

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
The bottom of the tower is bolted onto a reinforced concrete base with dimensions 5.2 x 5.2 x 0.6 m. This is set in a 1 m deep hole with a 0.4 m layer of hard-packed earth on top.
