Fixed speed induction generator
Did you know?
WebA fixed-speed induction generator is essentially identical to an induction motor, only it spins at above synchronous speed because it is being pushed around by the turbine, rather than pushing a load around. An induction generator is grid-excited, which means that the magnetic field that must be created by the generator’s stator windings is ... WebA critical speed controller for avoiding a certain rotational speed is presented. The controller is useful for variable speed wind turbines with a natural frequency in the operating range. The controller has been simulated, implemented and tested on an open site 12 kW vertical axis wind turbine prototype. The controller is based on an adaptation of the optimum …
