FIELD: electricity-producing industry.
SUBSTANCE: there is a known gas-driven turbine under fractional loads control mode, which includes the obtaining of the assignment of the gas-driven turbine capacity value, the gas-driven turbine shaft velocity measurement in real-time mode. In this mode for the predetermined capacity value according to the rotation velocity-gas-driven turbine capacity dependence diagram with respect to the minimum fuel one determines the commanded speed level of the gas-driven turbine shaft rotation, compares it with the current rotation velocity value and forms the instruction for the change in fuel and air supply into the gas-driven turbine combustor for the commanded speed level value achievement.
EFFECT: decrease in fuel consumption.
