POWER SUPPLY SYSTEM COMPRISING A HIGH-VOLTAGE DC TRANSMISSION DEVICE WHICH IS DIRECTLY SUPPLIED BY A PHOTOVOLTAIC POWER PLANT

摘要

A power supply system (SYS) and a photovoltaic device (PVE) intended therefor and comprising a plurality of DC voltage-generating photovoltaic modules (PVM) are proposed, wherein the photovoltaic modules (PVM) for generating a DC voltage (Udc*) exceeding the withstand voltage or dialectric strength (Umodmax) of the photovoltaic modules (PVM) and suitable for the high-voltage DC transmission are connected in parallel or in series to one another, wherein the power supply system (SYS) comprises a converter substation (UFS) that can be connected to a power supply network (SVN) installed for users, and includes a high-voltage DC transmission power line (HGUE) so as to transmit in the high voltage range the DC voltage (Udc*) generated by the photovoltaic device (PVE) to the converter substation (UFS).
