Photovoltaic-device for use in high voltage-direct current transmission path of power supply system, has set of photovoltaic modules arranged potential-symmetrically at central current bus bars

摘要

The device has a set of photovoltaic modules (PVM) producing direct current voltage that exceeds electrical strength of the photovoltaic-modules, where the photovoltaic modules are connected together in a parallel and/or serial manner. A set of module fields (MF plus, MF minus) is provided for a pole of the direct current voltage. The photovoltaic modules are arranged potential-symmetrically at central current bus bars (S plus, S minus), and the module field comprises a circular current collecting line (SR) that lies on a ground potential (EP).
