AEL-WPPI Wind Power Plants with Induction Generator Application

The Wind Power Plants with Induction Generator Application, "AEL-WPPI", has been developed by EDIBON to study the wind turbines electrical performance with three-phase induction generators of squirrel cage that inject power in the network.

Wind turbines with induction generator have some characteristics, of great interest to the students, which will be studied working with the machine in different regimes: sub-synchronous, synchronous and super-synchronous. Depending on the working regime of the induction generator, different electrical parameters can be analyzed. To analyze these electrical parameters, the Wind Power Plants with Induction Generator Trainer has an advanced network analyzer to will show the student, among others, the following parameters: positive and negative active, reactive and apparent powers (P, Q and S), line and total power factors, line currents, phase and line voltages, current and voltage harmonics, etc.

The wind turbine induction generator is coupled to the three-phase induction motor of squirrel cage in order to simulate different wind speeds. The three-phase induction motor is controlled by mean a frequency variator to vary the wind speed. On this way, the user can simulate different wind speeds and observes the response of the electrical generator coupled to the grid.

The Wind Power Plants Induction Generator Application has a series of sensors which allow the student to measure the wind turbine speed and the applied torque for it in order to calculate electrical and mechanical parameters, through which the student will go in depth about knowledge of wind turbines with induction generator.

This application has a power factor compensation module in order to analyze the effects of the reactive energy in the induction generator and the grid.

This application has all necessary electrical and mechanical safety elements.
