FIELD: power industry.
SUBSTANCE: invention relates to power industry. This is the method of gas-turbine plant operation in transient mode in which controller determines values of control command for mass-flow rate of incoming air, for fuel mass-flow rate, for mass-flow rate of water or steam, when water and steam are used; at least one command value is dynamically compensated in order to compensate various dynamics of supply systems for synchronisation of resulting changes in mass-flow rate of fuel, water, steam and combustion air delivered to combustion chamber, so that fuel-air mixture composition was within ignition zone. Also presented is a control system meant for implementation of proposed method, and gas-turbine plant including such control system.
EFFECT: providing fast operation in transient mode with consistent flame of premixed mixture.
