Abstract

See full text

In a method for black start of a power station including a plurality of inventers connectable to a local AC electrical grid, a first AC voltage is built up in the AC electrical grid by a first inverter, said first AC voltage being reduced in comparison with a rated voltage of the AC electrical grid by at least a quarter, and at least one second inverter is connected to the AC electrical grid after synchronization with the first AC voltage. After connection of the second converter, a second AC voltage, which is higher than the first AC voltage, is built up in the AC electrical grid.
