Patent

CA 2300201

A variable speed system for use in systems, such as, for example, wind turbines, is described. The system comprises a wound rotor induction generator (620), a torque controller (623) and a proportional, integral derivative (PID) pitch controller (1010). The torque controller controls generator torque using field oriented control, and the PID controller performs pitch regulation based on generator rotor speed.

L'invention concerne un système à vitesse variable destiné à des systèmes tels que des éoliennes. Le système comprend une génératrice à rotor bobiné (620), un régulateur de couple (623) et un régulateur de pas (PID) proportionnel, intégral et dérivé (1010). Le régulateur de couple régule le couple de la génératrice au moyen de commandes orientées champ, le PID assurant la régulation du pas sur la base de la vitesse du rotor de la génératrice.
