Wind Motor Control TRIZ Cases

Sliding pads fixed to the yaw ring spread uneven nacelle loads, cut pad wear, and allow easier replacement through radial access openings.

Cammed lock pins and a turnbuckle wedge into hub apertures to immobilize the wind turbine rotor with easier installation during maintenance.

A modular pitch carrier with strip plates and a ring increases hub size, improves stiffness, and enables safer ground-level assembly.

Automatically deployed UAVs disrupt airflow or attach to wind turbine blades to reduce shutdown oscillations with minimal manual intervention.

Rolling cam engagement with an eccentric shaft replaces gear teeth in wind turbine azimuth and pitch adjustment to cut wear and improve shock resilience.

Integrated strain gauges in a wind turbine pitch or yaw drive output shaft measure torque accurately without extra adapters or installation space.

A central controller coordinates multi-dimensional wind turbine setpoint changes to avoid undesirable operating points and reduce energy loss.

Global optimization sets power or torque curves by minimizing mechanical and electrical losses in wind and tidal energy converters.

Load monitoring and selective braking let a wind turbine reduce abnormal gear meshing loads without unnecessary shutdowns.

Non-horizontal torque arms support the drivetrain while reducing nacelle width and height and opening more space for access and handling.

A rotatable ducted cowl and stabilizing arms let a floating wind turbine self-align to wind and keep generating in harsh offshore conditions.

Wear debris data from gearbox oil guides blade pitch and yaw adjustments to slow wear, avoid shutdowns, and extend service life.

Variable-thickness reinforcement strengthens wind turbine pitch bearing stress hotspots, extending life while avoiding oversized rings.

An asymmetric coupling uses reverse-direction wind-up and frictional slip to absorb torque reversals and protect wind turbine gearbox bearings.

By rotating the nacelle to release pad pressure, this yaw bearing case enables crane-free gliding pad removal with lower maintenance cost and wear.

Multiple rotor locks and receptacles hold a turbine nacelle at precise 360° headings under high torque loads with lower brake weight and cost.

Spanwise contour surfaces with riblets and compliant materials disperse concentrated wake vortices, reducing induced drag, noise, and separation limits.

Curtailing turbine output from pitch motion and wind direction cuts mooring fatigue in floating wind turbines and can lower overdesign.

Global control optimization cuts mechanical and electrical losses to improve power output and overall efficiency in turbines.

A pivoting bracket, fastener, and damper let the tower and deck move relative to each other, reducing bending stress and easing retrofit installation.

Variable river or wind input is converted by Hummingbird and Kingfisher gear assemblies into constant-speed generation for stable grid frequency.

Sensor-based control identifies weather, contamination, and aging losses in each turbine, then adjusts operating parameters to stabilize wind farm output.

Machine learning infers wind shear from turbine operating data to adjust pitch and torque without LiDAR, improving output and load control.

A fluid-filled container with a moving damping body cuts wind turbine tower oscillations and fatigue loads without external power.

Separating the brake disk from the lubricated gliding yaw bearing preserves braking force, cuts contamination, and lowers wind turbine maintenance.

Patterned mating surfaces on the yaw pad and piston increase bond area and resist shear, reducing wear, deformation, and maintenance.
