ENERCON - Storm Control System

ENERCON wind energy converters run with a special storm control feature. This slows the wind turbine down so that it can continue to operate even at high wind speeds. Numerous shutdowns which lead to considerable losses in power output can thus be avoided. When storm control is activated, the rated speed is linearly reduced starting at a predetermined wind speed for each turbine type. Beginning at another turbine-specific wind speed, the limitation of the turbine`s rated speed also reduces active power. The turbine only shuts down at a wind speed of more than 34 m/s (10-minute average). In comparison: When storm control is deactivated, the wind turbine stops if the wind speed reaches 25 m/s in the three minute average or 30 m/s in the 15 second average.
