FIELD: engines and pumps.
SUBSTANCE: proposed method allows limiting power plant first output variable Msoll. Preset magnitude is set for second variable, preferably, rpm or speed. Actual magnitude of said second variable is defined. Preset magnitude is compared to actual magnitude. In case actual magnitude does not exceed preset one, first variable Msoll is limited by first magnitude Mzul. In case actual magnitude exceeds preset one, output variable Msoll is limited by second magnitude smaller than first Mzul. Invention covers also power plant control device.
EFFECT: ruled out emergent engine shutdown on exceeding preset rpm or speed.
