Wind Motor Control TRIZ Cases
- VSM Wind Turbine Damping Control via Line Side Converter Power
Active power modulation through the line side converter damps drive train oscillations in VSM wind turbines while preserving stability.
- Converter Feed-In Control Based on Grid Converter Share
Estimating local converter share lets wind or converter-based feed-in adapt frequency and voltage support to stabilize weak grids.
- Wind Turbine Converter Control for Mechanical Oscillation Damping
Separate generator and grid-side control signals hold torque constant at high-frequency speed ripples to damp oscillations and cut drive train load.
- Wind Plant Inertial Response Control Without Secondary Frequency Dip
Timed storage release sustains wind plant power during turbine inertia recovery, preventing a secondary grid frequency dip.
- Offshore Wind Turbine Auxiliary Control for Grid Restart
An auxiliary turbine control mode and substation backup generator form a weak grid, enabling offshore wind park brown and black starts after faults.
- Wind Turbine Power Control Under Mechanical Load Limits
Grid-responsive power control limits wind turbine mechanical stress while preserving feed-in flexibility and service life.

- Half-Gear Rotary Machine for Higher Torque Energy Conversion
A half-gear drum and revolving rack-driven gears raise torque efficiency and improve wind or water power conversion.
- Wind Turbine Fallback Power Control During Communication Loss
When plant communication fails, the turbine shifts to a fallback power set point with controlled ramping to sustain output and grid stability.
- Wind Turbine Shutdown Using Generator Torque Before Blade Pitch
Generator torque slows the rotor before blade pitch changes, reducing asymmetric blade loads and shutdown fatigue in wind turbines.
- Reactive Power Control Using Electrical Distance in Wind Networks
Electrical-distance-based reactive power estimation helps wind installations supply grid support more accurately for voltage regulation and stability.
