Factors affecting wind turbine cut in speed

Click For Summary
SUMMARY

The cut-in speed for small wind turbines, particularly those utilizing a single bearing on the rotating axis and a permanent magnet generator, is typically set at 3 m/s. This speed is crucial for the turbine to begin generating electricity efficiently. The conversion of 3 m/s is approximately 10.8 km/h or 6.7 mph, which is essential for understanding operational thresholds. Design considerations for achieving this cut-in speed include rotor diameter, blade pitch, and generator characteristics.

PREREQUISITES
  • Understanding of wind turbine mechanics
  • Knowledge of permanent magnet generator functionality
  • Familiarity with aerodynamic principles related to rotor design
  • Basic calculations involving wind speed and energy conversion
NEXT STEPS

Hello, could someone explain some of the factors, or the calculation, for determining wind turbine cut in speed? I am talking about small wind turbines using with a single bearing on the rotating axis and a permanent magnet generator. A lot of literature targets a cut in speed of 3 m/s without explaining how to design for this value.

3 m/s
How fast is this in more familiar units (mph, kmph)?
