Title (EN) METHOD FOR OPERATING AN ELECTRICAL SYSTEM
(FR) PROCEDE D'EXPLOITATION D'UN SYSTEME ELECTRIQUE
Abstract:
(EN) A method for operating an electrical system (20) for a machine (10) is provided. The electrical system may include at least one power source (30) connected to a power-distribution network (21). The power-distribution network may include a first portion (26) with one or more power loads (34) connected thereto and a second portion (28) with one or more power loads connected thereto. The method may include repeatedly executing a load-priority cycle including operating in a first load-priority mode and subsequently operating in a second load-priority mode, during a power deficit. Operating in the first load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the first portion. Operating in the second load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the second portion.
(FR) L'invention porte sur le procédé d'exploitation du système électrique (20) d'une machine (10), comprenant au moins une source d'énergie (30) reliée à un réseau de distribution (21). Un tel réseau peut comporter une première partie (26) où se trouvent plusieurs charges, et une deuxième partie (28) où se trouvent plusieurs charges. Le procédé consiste à exécuter répétitivement, en cas de déficit de puissance, un cycle de priorité de charges fonctionnant alternativement dans un premier mode de priorité de charge, puis dans un deuxième mode de priorité de charge. Dans le premier mode les deux sections sont alimentées avec priorité donnée à la première section, et dans le deuxième mode les deux sections sont alimentées avec priorité donnée à la deuxième section.
