FIELD: engines and pumps.
SUBSTANCE: invention can be used in electronic systems (ACS) of automatic control of gas-turbine units (GTU) of gas-compressor plant (GCP) and gas turbine electric power stations (GTEPS). Additionally during the process of GTU start there measured is a frequency of GTU starter output shaft rotation and it is compared to pre-set value defined for each type of starter by calculation-experimental method. If measured frequency is higher than pre-set value, oil pressure in oil supply line to starter is measured and compared to pre-set value defined for each type of starter by calculation-experimental method. If oil pressure is lower than pre-set value, the signal "Stop of starting by low pressure oil at starter input" is formed and GTU emergency stop is performed.
EFFECT: increase of GTU technical condition control quality and improvement of GTU, GCP and GTEPS operating reliability.
