Wind Energy Recovery

In a typical wind turbine application, a propeller rotates an induction motor - (in this case “induction generator”) at a speed that varies with wind velocity. The slight sub-synchronous frequency of the inverter guarantees the motor functions as a generator at all times.

Affinity laws of fan operation define the power produced to increase as a cube of wind speed. Parker SSD Regenerative IGBT Drives smoothly distribute this newly generated power onto the power grid at a constant 60Hz, regardless of speed.
