Turbine Control Equipment

for Distributed Wind Energy Resources (DWER)

 

DWER Power Conversion and Turbine Control Equipment

Windurance offers a portfolio of integrated, interoperable, Distributed Wind Power Conversion and Recognized Turbine Control components for wind turbine OEMs serving the North American markets. These components are being developed by Windurance, within the distributed wind energy community, and under the guidance and shared investment of the U.S. Department of Energy’s National Renewable Energy Laboratory’s Distributed Wind Energy CIP program.

WIND-90-480-C Wind Turbine Power Converter

This Distributed Wind Energy Resource (DWER) component pulls wind energy from the wind turbine generator, “converting” it into DC electrical power. DC power feeds other DWER components to control and convert wind energy into certified grid support utility interactive electric power service standards.

  • 90kW nominal power rating
  • 480V nominal generator voltage
  • Latest high-efficiency SiC FET device technology
  • Works with three-phase synchronous and asynchronous generators
  • CAN bus network provides real-time conditions and control data
  • Generator torque/speed command and control
  • Supports parallel connection for up to 160kW and 240kW rated wind turbine generators
  • Available outdoor enclosure configuration

WIND-90-480-I Wind Turbine Power Inverter

This Distributed Wind Energy Resource component “inverts” DC power from the converter, or storage, into three-phase AC power to the local utility grid connection AC power that connects and delivers power to the local utility grid consumers.

  • 90kW nominal power rating
  • 480V three-phase grid support utility interactive connection
  • Advanced Inverter Certification: UL 1741 SA or SB
  • Latest high-efficiency SiC FET device technology
  • CAN bus network provides real-time conditions and control data
  • Supports parallel connection for up to 160kW and 240kW rated wind turbine generators
  • Available outdoor enclosure configuration

WIND-140-850-D Wind Turbine Diversion Load Controller

This Distributed Wind Energy Resource component “diverts” power being produced by the wind turbine generator that is in excess of power that can be delivered to the grid, or to storage. It provides braking energy to facilitate wind turbine control during abnormal grid conditions.

  • 140kW nominal power rating
  • Parallel and safety backup operation
  • Serves as a convenient DC bus power distribution junction
  • External load is scalable according to wind turbine design requirements
  • Available outdoor enclosure configuration

WIND-STORE-48 Energy Storage Charge Controller

WIND-STORE is a bidirectional energy flow controller. Connecting one side to the power conversion DC bus and the other to an energy storage element, such as a battery, wind energy produced by the wind turbine in excess of grid demand flows into storage seamlessly according to the characteristics of the battery. When wind energy production falls below the grid demand, energy flows seamlessly from the battery to supplement reduced wind power output.

 

 

  • Latest high-efficiency SiC FET device technology
  • Scalable in small increments to optimize application storage dimensions
  • 48V OSHA touch safe voltage level
  • CAN bus network provides real-time conditions and control data

WIND-CON-23 Wind Turbine Controller Platform

This UL 6141 and UL 6142 recognized component provides wind turbine OEMs with pre-certified wind turbine controller hardware and software framework upon which their unique wind turbine design features and characteristics can be implemented. Pre-integration of a range of IO and wind turbine-specific instruments and sensors, including Windurance power conversion equipment network, facilitates the development, integration, and certification of the whole wind turbine system as a DWER.

 

 

  • Safety Standard UL1998 software framework
  • Standard UL 6141 and UL 6142 component turbine safety hardware and software
  • Certified IEEE 2030.5 grid support utility interactive (UL 1741 SB with Windurance Inverters)
  • Interface to wind system control, production, condition data through cloud web services cyber secure for multilevel user access
  • Capability to embed aeroelastic code, such as NREL FAST provides advanced turbine control and life cycle performance monitoring
  • Open architecture software framework for OEM proprietary turbine designs and development
  • Local and distributed IO hardware and software interfaces for popular/standardized wind industry instruments for wind speed, direction, over speed, vibration, temperature, speed, position, and more
  • Power conversion control and data network

miniPitch Collective and Individual Brushless Pitch Actuator Sub-System

This miniaturized brushless servo pitch actuator is for collective and individual regulated wind turbines. Designed specifically for the distributed wind turbines, the miniPitch design leverages more than two decades of Windurance experience in servo pitch actuator applications. The low-cost design brings advanced control capability common on modern utility-scale wind turbines within reach of smaller scale turbines in the DWER space.
