Title:
DEVICE FOR SUPPLYING ENERGY TO AN ELECTRIC OPERATING GRID AND TO ADDITIONAL CONSUMERS FROM A BATTERY-ASSISTED SUBSTATION
Document Type and Number:
WIPO Patent Application WO/2018/167286
Kind Code:
A3
Abstract:
The invention relates to a device for supplying energy to an electric operating grid (2) for electrically driven short-haul transport means (103, 104) having continuous power withdrawal, the device having a substation (1, 1', 5 100, 100') with the following elements: a DC voltage circuit (8), which is connected to a power grid (5) by means of a first inverter (6); and a first feed system (10, 11) for the operating grid (2), said system being connected to the DC voltage circuit (8). The device can also have one or more second feed systems (13, 13', 13'', 13''') connected to the DC voltage circuit (8) for supplying one or more additional consumers, in particular charging stations, and a stored energy source (9) which is connected to the DC voltage circuit by a bidirectional coupling system (12). The second feed systems can be galvanically insulating and configured to control the output voltage or the output current. Specific requirements of the additional consumers in terms of operating voltage and insulation can be addressed by an appropriate design of the second feed systems (13, 13', 13'', 13''').
