TURBO-GENERATOR CONTROL METHOD Russian patent published in 2020 - IPC F02C9/00 F01D1/00 F01D21/02 

FIELD: engine building.

SUBSTANCE: invention relates to gas turbine engine building and can be used in automatic control systems of gas turbine engines, including those used in gas turbine plants. In the turbine generator control method, in which the fuel turbine generator rotational speed measured value is used to maintain the turbo generator rotor preset rpm, turbo generator rotor acceleration signal is generated, according to the present invention, a threshold is selected from the turbo-generator rotor rpm in the range between the turbo-generator rotor turbo generator specified and maximum tolerable values, generating turbo generator rotor rpm forecast signal as sum of current turbo generator rotor rpm and turbo generator rotor acceleration signals taken with preselected gain, comparing prediction signal with selected threshold and, if it exceeds threshold, fuel consumption is reduced in proportion to difference between prediction signal and selected threshold, and if the turbine generator rotor rpm signal or the turbine generator rotor rpm rotation signal exceeds the preset maximum allowable value, the fuel supply is stopped.

EFFECT: wider range of disturbances, which can be parried without operation of protection at maximum permissible rotation frequency, and increase in system non-failure operation.
