SYSTEM AND METHOD FOR STOICHIOMETRIC EXHAUST GAS RECIRCULATION GAS TURBINE SYSTEM Russian patent published in 2019 - IPC F02C9/28 

FIELD: electricity.

SUBSTANCE: invention relates to power engineering. In the method, a non-transitory, computer readable medium stores instructions executable by a processor of an electronic device. Said instructions include instructions to determine that a transient event is occurring in an electrical grid coupled to an exhaust gas recirculation gas turbine system, wherein the transient event is an under-frequency or an under-voltage event. In addition, these instructions include instructions to increase a flow rate of fuel to a combustor of the exhaust gas recirculation gas turbine system in response to the transient event, when the exhaust gas recirculation gas turbine system is operating in a non-stoichiometric combustion mode. Further, these instructions further include instructions to increase a flow rate of oxidant to the combustor before increasing the flow rate of fuel to the combustor, or to decrease a local consumption of the electrical power so as to increase a portion of the electrical power that is exported to the attached electrical grid, or both, in response to the transient event when the exhaust gas recirculation gas turbine system is operating in a stoichiometric combustion mode.

EFFECT: invention makes it possible to increase the efficiency of electric power generation.
