PHOTOVOLTAIC SYSTEM AND METHOD FOR OPERATING A PHOTOVOLTAIC SYSTEM FOR FEEDING ELECTRICAL POWER INTO A MEDIUM-VOLTAGE NETWORK |
摘要 |
<p>The disclosure relates to a method for operating a photovoltaic system for feeding a medium-voltage grid, wherein the photovoltaic system has a photovoltaic generator including a plurality of photovoltaic modules, at least one inverter and at least one medium-voltage transformer. The medium-voltage transformer is connected on the primary side directly to a low-voltage AC output of the inverter, the inverter is connected to the photovoltaic generator via a DC input, and the inverter permits reverse currents from the low-voltage AC output to the DC input. The method is characterized by the fact that in the event that there is insufficient generation of electric power for the feed by the photovoltaic modules, the inverter remains connected on the AC side to the medium-voltage grid via the medium-voltage transformer, and remains connected on the DC side to the photovoltaic generator.</p> |
