Abstract
A reliable and flexible black start network restoration for a combined cycle power plant can be achieved by synchronizing a steam turbine and ramping that steam turbine up to an operating point where a maximum power increase is achieved. The resulting steam turbine load change can be compensated by the gas turbine. The increase in the demanded load can be provided by the steam turbine. The load of the steam turbine can also be gradually reduced to increase its load-increasing capacity.
