Abstract
A local power supply system having a grid transfer point for the connection of an energy supply grid has a first transmission line for transmitting electrical energy from the grid transfer point to a first terminal for connecting an arrangement of consumers, and a second transmission line for transmitting electrical energy between the grid transfer point and a second terminal for connecting an arrangement of energy stores. A first disconnector is arranged in the first transition line between the grid transfer point and the first terminal, and a second disconnector is arranged in the second transmission line between the grid transfer point and the second terminal. A coupling device, which electrically connects the first terminal and the second terminal, has a first switch and a second switch connected in series thereto, wherein a coupling element is arranged between the two switches connected in series, which coupling element has a grounding apparatus, a phase connection apparatus, a neutral conductor connection apparatus, a connection to a diesel generator and/or an apparatus for generating a neutral conductor potential. The disclosure also relates to a method for operating such a system.
