Abstract

A casing air temperature Ta and a steam temperature Ts are measured, and if an absolute value ΔT of a difference between these two temperatures is within a predetermined temperature, the gas turbine is connected to the generator. After the connection is done, the load is gradually increased, and the coolant changeover signal is sent from a processor to a controller. The coolant is then changed to the steam, thereby completing the connection of the gas turbine with the generator and the changeover of the coolant.
