Abstract

Die Erfindung bezieht sich auf eine Lösung für eine multilokale Stromeinspeisung in einen Verbraucherstromkreis (1), welcher mindestens zwei an unterschiedlichen Stellen angeordnete Stromeinspeisungspunkte (2, 3), nämlich einen zentralen Stromeinspeisungspunkt (2) und mindestens einen dezentralen Stromeinspeisungspunkt (3) aufweist, wobei für den Verbraucherstromkreis (1) ein zulässiger Stromhöchstwert festgelegt ist. An dem zentralen Stromeinspeisungspunkt (2) ist der Verbraucherstromkreis (1) durch einen Leitungsschutzschalter (4) gegen ein Überschreiten dieses Stromhöchstwertes abgesichert. An den dezentralen, nicht mit einem Leitungsschutzschalter (4) ausgestatteten Stromeinspeisungspunkten (3) wird in Echtzeit der jeweils über diese Stromeinspeisungspunkte (3) eingespeiste Strom gemessen. Die gemessenen Ströme werden mittels einer Verarbeitungseinheit (6) aufsummiert. Schließlich wird der Nennstrom des als elektronisch steuerbarer Schalter, ausgebildeten Leitungsschutzschalters (4) mittels der Verarbeitungseinheit (6) in Echtzeit so variiert, dass sein jeweiliger augenblicklicher Nennstrom auf einen Wert eingestellt wird, welcher jeweils der Differenz aus dem für den betreffenden Verbraucherstromkreis (1) festgelegten Stromhöchstwert und aus der Summe der dezentralen Stromeinspeisungspunkten (3) gemessenen Ströme entspricht.
