FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Water vapor circulation loop includes a high pressure turbine, a condenser and a steam generator. Steam generator is connected to the high-pressure turbine via first line of the pipeline. In the direction of steam between the steam generator and the high-pressure turbine, for the high-pressure turbine power supply fresh steam emergency valves and fresh steam valves are installed. In the direction of steam downstream of the high-pressure turbine, a pipeline starting line is installed connecting the exhaust steam zone downstream of the high-pressure turbine to the condenser. Installed at least one control device regulating, depending on the high-pressure turbine speed, temperature and load the start-up valve closing for the pipeline starting line closing and the fresh-steam valves opening. By means of the loop, the operation method is implemented, in particular, the steam turbine start-up.
EFFECT: invention allows to increase the turbine start-up efficiency.
