Embodiment Construction

[0020] figure 1 It is a structural diagram of the photovoltaic device PVE of the present invention, which produces a DC voltage Udc in the high voltage range * And feed it into the high voltage transmission line HGUE. It can also be used for short-distance power transmission. At this time, the Lines are implemented as cables. For this purpose, the photovoltaic system PVE comprises two module fields MF+ and MF−, which each have a centrally arranged bus bar S+, S−, so that they respectively form the positive and negative electrical connections. Each of the module fields (here MF+ is used as an example) is symmetrical with respect to the centrally arranged busbar S+ structure. The module field MF+ contains multiple PV modules (see also image 3 a), the photovoltaic modules are connected one by one to form a plurality of photovoltaic modules or module modules, which in turn are connected to form a plurality of basic structures BS, which preferably correspond to modules connec...

Abstract

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).

Description

technical field [0001] The invention relates to a photovoltaic device according to the preamble of claim 1 . The invention relates in particular to a photovoltaic installation connectable to a high voltage direct current transmission line, suitable for supplying electrical consumers arranged remotely or close to said photovoltaic installation. Background technique [0002] Photovoltaic installations or photovoltaic units are increasingly used in so-called photovoltaic power plants, which are mostly installed in sunny areas and are used to centralize the power supply network for existing electrical equipment that is usually set up far away from photovoltaic installations or photovoltaic units. generate electricity. Such photovoltaic installations are preferably designed for large areas, for example in desert areas, in order to be able to reliably generate electricity from the sun. This type of unit is also called "very large-scale photovoltaic system", referred to as "VLS-P...
