<p>The solar power plant (1) has multiple photovoltaic modules (2) for generating energy supplied in multi-phase power supply network. Multiple photovoltaic-strings (3a to 3c) assigns different phases (L1 to L3), are connected with a primary side of a power transformer (4). An additional direct current voltage source (6) is attached between a neutral conductor (N) and ground (PE), such that a potential of the photovoltaic-strings are shifted and a bias voltage is slidably adjusted from zero volt.</p> |
