OVERVIEW

Design

characteristics

Wind Turbine Blades Profiles optimized using CFD simulations and made with the latest resin compounds based on acrylic urethane and epoxy in combination with composite carbon and glass fibre.
1
Variable Pitch Blades Patented, active variable pitch system with passive safety features offers accurate control of the position of the blades and protects automatically in case of system failure.
2
Generator
Permanent magnet generator of 40 poles, 20 kW maximum power at 120 rpm and 1,700 Nm provides a high level of energy performance.
3
Anemometer Wind speed sensor accurately tracks the behaviour of the wind in real time, in order to improve the turbine’s performance and safety. 5 Controller & Monitoring
Configurable controller electronics allows the turbine to adapt to the type of grid or batteries connected, providing maximum energy generation. Remote Monitoring ensures the wind turbine is operating at its peak performance at all times.
6
Hydraulic Blade Control
Hydraulic system based on a highly precise position sensor determines the position of the blades according to the control algorithms.

Reliability & Safety

SAFETY

  • Second Level: Electronic control system activates mechanical brake with shaft lock and electromagnetic induction brake.
  • Third Level: Passive springs deploy, putting the turbine blades in a stall position, spoiling the rotor
    aerodynamics and subsequently its ability to rotate.

DATA INPUT & MANAGEMENT

  • Remote Control: Allows the remote customization of the wind turbine to provide the optimum performance at every site.
  • Storm Detection: Intelligent storm detection algorithm and automatic safety lock protects the turbine in the event of dangerous gusts/hurricane weather.
  • LCD display in control box. Can output to local PC or be monitored remotely via the internet.

CONSTRUCTION & MAINTENANCE

  • Anti-Corrosive Blades: The blades and nacelle are treated with epoxy paint and hermetically sealed. This gives corrosion and saline protection, making the turbine ideal for island, coastal or desert deployments.
