Abstract

An electric power system includes a direct voltage rail (), battery elements (-) connected with supply-converters (-) to the direct voltage rail, and load-converters (-) for converting direct voltage of the direct voltage rail into voltages suitable for loads of the electric power system, where the supply-converters and the load-converters are connected with over-current protectors (--) to the direct voltage rail. The electric power system further includes a capacitor system () connected to the direct voltage rail and capable of supplying fault current for switching an over-current protector into a non-conductive state in response to a fault causing a voltage drop at an electrical node connected to the direct voltage rail via the over-current protector. The capacitor system may include one or more high-capacitance electric double layer capacitors. The fault current available from the capacitor system enables a selective protection.
