Reliability & Safety

SAFETY

  • Base Level: Active blade pitch control, with 90º of movement, limits power output and can put blades in a total stall position.
  • Second Level: Electronic control system activates mechanical brake with shaft lock and electro-
    magnetic 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.
  • Ryse Energy service and maintenance contracts available.
