Use cases and value proposition
Wind turbine OEM solution
Wind turbine OEMs can enhance their turbines with the VYND C1. It provides the full integration of the lidar into the controller with feedforward control signals. Lidar-assisted control support operation through an improved rotor speed regulation and a reduction of fatigue and extreme loads during operation. Furthermore, a specific wind turbine design can be applied to more turbulent sites (i.e. Class B turbine at Class A site) because of the increased control performance.
The C1 is a fully customizable, easy-to-use interface to enable lidar-assisted control. The wind turbine OEM can customize the expected feedforward behavior based on the wind turbine design.
Key added values
- Fatigue load reduction on thrust-driven components (tower, blades)
- Extreme load reduction
Key features
- Customizable feedforward controller
- Extraction of wind preview for additional usage in the control system
- Wind speed estimator based on SCADA data
- Live monitoring of preview quality and control performance
Retrofit solution
The retrofit solution uses data from the SCADA and its pre-configuration to determine the optimal data processing and feedforward controller without the need of a wind turbine model. Wind farm owner can retrofit their wind turbines with the VYND solution. It reduces the downtime due to generator speed overshoot shutdowns, decreases structural loads and extends the wind turbines’ lifetimes.
The retrofit solution is a data-driven feedforward controller. It uses the SCADA data and pre- configured information to design the control strategy.
Key added values
- Fatigue load reduction on thrust-driven components (tower, blades)
- Extreme load reduction
- Lifetime extension
- Less downtime due to overspeed
Key features
- Data-driven feedforward controller (no model is needed)
- Wind speed estimator based on SCADA data
- Live monitoring of preview quality and control performance
Floating wind turbine solution
With the floating wind solution VYND is addressing the special needs of floating wind by adding special software and additional sensors. Due to the system limitations the feedback controller benefits most from the lidar feedforward controller. Several studies have shown the added value and the high potential in load reduction lidar-assisted control offers for floating wind turbines.
Key added values
- Reduction of thrust-driven fatigue loads, which are becoming more important for large rotors up to 10-15 MW (blades, drivetrain, tower, moorings).
- Real-time information of rotor-effective wind speed allows a real-time load monitoring with minimum uncertainty. This information is necessary for a low-risk commissioning and operation.
Key features
- Data-driven feedforward controller (no model is needed) or fully customizable feedforward controller
- Extraction of motion compensated wind preview for additional usage in the control system
- Wind speed estimator based on SCADA data
- Live monitoring of preview quality and control performance
