(DE) KOPPLUNG EINES DURCH EIN PRIMÄRBEWEGUNGSGLIED ANGETRIEBENEN GENERATORS MIT EINEM BESTEHENDEN STROMNETZ
(EN) INTERFACING A PRIME MOVER DRIVEN ALTERNATOR WITH AN EXISTING POWER NETWORK
(FR) LIAISON ENTRE UN ALTERNATEUR ENTRAÎNÉ PAR UN ÉLÉMENT MOTEUR ET UNE ALIMENTATION ÉLECTRIQUE EXISTANTE
Abstract
(EN)
To interface a prime mover driven alternator (20) with an alternating current network, an electronic load (80) connected in parallel with the prime mover driven alternator (20) is activated as part of a transition between a disconnected state and a connected state. The disconnected state is when the prime mover driven alternator is electrically isolated from the alternating current circuit and the connected state is when the prime mover driven alternator is electrically coupled to the alternating current circuit.

(FR)
Selon l'invention, pour relier un alternateur (20) entraîné par un élément moteur à un réseau à courant alternatif, une charge électronique (80) reliée en parallèle à l'alternateur (20) entraîné par un élément moteur est activée lors d'une transition entre un état déconnecté et un état connecté. L'état déconnecté est l'état dans lequel l'alternateur entraîné par un élément moteur est isolé électriquement du circuit à courant alternatif, et l'état connecté est l'état dans lequel l'alternateur entraîné par un élément moteur est couplé électriquement au circuit à courant alternatif.
