METHOD OF OPERATION OF COMBINED POWER STATION Russian patent published in 2014 - IPC F01K23/00 F02C9/00 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. In the method of operation of combined power station comprising the gas turbine and the steam turbine, respectively by means of connected electric generator AC voltage of the relevant frequency is generated and supplied to the AC mains, and the off-gas of the gas turbine is used for generation of steam for the steam turbine. At the first stage the internal consumers are supplied in independent mode by means of gas turbine, and its regime point is selected so that the steam minimum temperature for the steam turbine is achieved, at the second stage in independent mode the steam turbine is synchronized and is started up to the working point, at which the maximum increase of the load can be achieved, and the resulting change of the load of the steam turbine is compensated by the gas turbine, at the third stage the loads of consumers are connected, at the fourth stage increase of the requested load completely or partially, and also continuously or temporarily is provided by the steam turbine, at the fifth stage the load of the steam turbine is gradually decreased for increase of its ability to stand the load increase. The stages from third up to fifth are reproduced until the base load of combined power station will be achieved.

EFFECT: invention allows to provide reliable and flexible recovery of the mains at emergency start.
