FIELD: pipeline engineering.
SUBSTANCE: method comprises filtering gas, reducing gas pressure, supplying fuel to the stop valve that shuts off the fuel flow when the speed of rotation of the power plant exceeds 105% of the maximum value, and control of the batcher of gas by means of a control unit from the current difference between the reference signal and signal from the pickup of the position of the batching member according to the formula presented. The device comprises filtering system, system for lowering pressure of the gas fuel supplied to the power plant, and system for control of supply of the gas fuel to the power plant. The control system has shutoff valve connected with the batcher that is controlled by the control unit on commands from the electronic controller, and valve for emergency stop that interacts with the gas batcher.
EFFECT: enhanced reliability and prolonged service life.
