Integrated SkelMod ultracapacitor module - increased safety, reliability & turbine uptime

Benefits of our solution

  • Increased safety, reliability & turbine uptime
  • Pitch check operation frequency reduced
  • Active blade oscillation damping situations have no impact

Challenge

100% reliable back-up energy solution

  • Background
  • Turbine shall stop rotating in case of power failure or unsafe wind speed
  • The blades shall rotate towards neutral angle with respect to the airflow
  • Pitch control system enables it without connection to the main power
  • 100% reliable back-up energy storage
  • Key Challenges
  • Unreliable and complex hydraulic technology
  • Unpredictable lead-acid powered systems
  • known consequences
  • Catastrophic failures of the wind turbine
  • Heavy maintenance of hydraulic or lead-acid battery-powered pitch control systems
  • Hydraulic systems troubleshoot difficulties
