Title (EN) HARMONIC CONTROL
(FR) COMMANDE HARMONIQUE
Abstract:
(EN) There is provided a method and apparatus for controlling harmonics. For each device in an array of devices, a level of harmonic control is acquired to apply to an alternating current voltage powering the device. The level of harmonic control defines a period in a cycle of the alternating current voltage in which to drop the alternating current voltage. For each device in an array of devices, the alternating current voltage powering the device is controlled by dropping the alternating current voltage in the period defined by the acquired level of harmonic control.
(FR) L’invention concerne un procédé et un appareil de commande d’harmoniques. Pour chaque dispositif d’un ensemble de dispositif, un niveau de commande harmonique est acquis pour être appliqué à une tension alternative alimentant le dispositif. Le niveau de commande harmonique définit une période d’un cycle de la tension alternative dans laquelle il faut faire chuter la tension alternative. Pour chaque dispositif d’un ensemble de dispositifs, la tension alternatif alimentant le dispositif est commandé par une chute de tension alternative dans la période définie par le niveau acquis de commande harmonique.
