Résumé

This paper deals with a fixed-frequency variable-speed motor/generator with 3-level VSI (Voltage Source Inverter) cascade. The 3-level VSI is applied to a DASM (Doubly-fed ASynchronous Machine) for large pump storage plants. The extension to 3 levels is the original part of this paper. The whole system behavior has been simulated using the “SIMSEN” simulation software. This paper focuses on the simulation results and also on the comparison with the 12-pulse cyclo-converter topology.

Variateur électronique de vitesse

thumb|Petit variateur de vitesse thumb|Électronique du variateur de vitesse ci-dessus Un variateur électronique de vitesse (en anglais, variable frequency drive ou VFD) est un dispositif destiné à régler la vitesse et le couple d'un moteur électrique à courant alternatif en faisant varier respectivement la fréquence et la tension, délivrées à la sortie de celui-ci. Leurs applications vont des plus petits aux plus grands moteurs, comme ceux utilisés par les perceuses.

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

Motor drive

Motor drive means a system that includes a motor. An adjustable speed motor drive means a system that includes a motor that has multiple operating speeds. A variable speed motor drive is a system that includes a motor and is continuously variable in speed. If the motor is generating electrical energy rather than using it – this could be called a generator drive but is often still referred to as a motor drive. A variable frequency drive (VFD) or variable speed drive (VSD) describes the electronic portion of the system that controls the speed of the motor.
