J965e: Single doubly fed induction machine controlled with slip power dissipation in an internal resistor..


Single doubly fed induction machine controlled with slip power dissipation in an internal resistor

A number of turbines, ranging from 600 kW to 2.75 MW, have the variable-speed conditions are achieved dissipating the energy within a resistor placed in the rotor, as shown in Figure. Using that technology, the efficiency of the system decreases when the slip increases, and the speed control is limited to a narrow margin. This scheme includes the power converter and the resistors in the rotor. Trigger signals to the power switches are accomplished by optical coupling
