Abstract
A method for the start of a power plant installation which includes a gas turbine, a generator coupled to the gas turbine, and a frequency converter to feed current into an electrical grid. In accordance with the method, during the start of the gas turbine, the generator is connected to the electrical grid via the frequency converter before the operating rotational speed of the gas turbine is reached, wherein the frequency converter is controlled such that it generates an output current with the grid frequency. A power plant installation can execute the above method.
