Kurzfassung
Um die Energieeffizienz von Maschinen zu steigern, ist eine Kenntnis des elektrischen Energieverbrauchs auf Komponentenebene notwendig. Dazu wird normalerweise an jeder Komponente ein Messsensor installiert, was jedoch hohe Hardware- und Installationskosten verursacht. Eine alternative Messmethode ist das sogenannte Non-intrusive Load Monitoring, welches in Privathaushalten bereits erfolgreich eingesetzt wird. In diesem Beitrag wird untersucht, wie geeignet die Methode für in der Fertigungsindustrie eingesetzte Maschinen ist.
Abstract
In order to increase the energy efficiency of machines, knowledge about the electricity consumption of the machine components is necessary. Therefore a measurement sensor is installed at each component usually, which results in high hardware and installation costs though. An alternative measurement method is the so called non-intrusive load monitoring, which has already been successfully applied in private homes. In this paper it is analyzed, in how far the method can be applied to manufacturing machines.
