FIELD: engines and pumps.
SUBSTANCE: invention my be used in gas turbine engine ACS electronic circuitry. Said gas turbine engines have free turbine and are operated integrated with gas turbine units to drive electric generators of gas turbine electric power stations. Novelty of proposed invention consists in that free turbine rpm setting is additionally increased unless frequency of voltage generated by electric generator increases supply circuit voltage by magnitude that exceeds self-synchroniser frequency tolerance before synchronising electric generator with unlimited-power supply circuit and before cutting in electric generator to parallel operation.
EFFECT: higher efficiency of electric power station thanks to higher quality of ACS operation.
