Title (EN) A METHOD FOR ESTIMATING MOTOR PARAMETER IN A LOAD COMMUTATED INVERTER ARRANGEMENT, AND A LOAD COMMUTATED INVERTER ARRANGEMENT THEREFOR
(FR) PROCÉDÉ POUR L'ESTIMATION DE PARAMÈTRE DE MOTEUR DANS UN AGENCEMENT D'ONDULEUR COMMUTÉ PAR CHARGE, ET AGENCEMENT D'ONDULEUR COMMUTÉ PAR CHARGE CORRESPONDANT
Abstract:
(EN) The present invention relates to a method for estimating a motor parameter in a load commutated inverter arrangement, comprising the steps of: measuring a motor side ac-voltage; detecting commutation interval information of the measured motor side ac-voltage; estimating a motor parameter based on the detected commutation interval information; and indicating when the estimated motor parameter deviates from a monitoring parameter thereof.
(FR) La présente invention concerne un procédé pour l'estimation de paramètre de moteur dans un agencement d'onduleur commuté par charge, comprenant les étapes suivantes : la mesure d'une tension alternative côté moteur; la détection d'information d'intervalle de commutation de la tension alternative mesurée côté moteur; l'estimation d'un paramètre de moteur basée sur l'information d'intervalle de commutation détectée; et l'indication de l'instant de la déviation du paramètre de moteur par rapport à un paramètre de contrôle de celui-ci.
