(FR) PROCÉDÉS ET SYSTÈME DE SURVEILLANCE DE CHARGE NON INTRUSIVE
Abstract
(EN)
Identification and tracking of major electric appliances by using aggregate power data obtained at the main breaker level of a residence or commercial establishment. Step power changes and power surges characterize appliances. These features are identified and the time of use and duration statistics are considered to match an observed sequence of power changes with the appliances being turned on and off. The time-dependent usage of appliances and their power consumption are then reconstructed.
(FR)
La présente invention concerne l'identification et la localisation d'appareils électriques principaux au moyen de données de courant agrégées obtenues au niveau du disjoncteur principal d'une résidence ou d'un établissement commercial. Des variations soudaines et des sautes de courant caractérisent les appareils. Ces caractéristiques sont identifiées et le temps d'utilisation et les statistiques de durée sont pris en considération pour mettre en correspondance une séquence observée de variations de courant avec les appareils allumés et éteints. L'usage en fonction du temps des appareils et leur consommation de courant sont alors reconstruits.
