What are rotor startup/shutdown speeds?
Cut-in condition is around 4.5m/s and the turbine will shut down in the event of sustained wind speeds over 16m/s. The qr5 is a ‘lift-type’ turbine and needs to operate at a specific tip-speed ratio to produce maximum power. The turbine is equipped with an anemometer, and if the control system determines that sufficient wind exists for operation, the turbine is actively spun-up to operating conditions at which point it enters lift-mode and starts extracting energy from the wind.
