摘要

For the 1200-MW power unit of the Kostroma SRPP, the lower limit of the lower range limit is 800 MW. This article presents the results of static field tests in unloading the power unit to 700 MW. Static and dynamic trials at the minimally achievable load with perturbations in the operating environment and fuel flow rate showed the reliability of operation of the power unit equipment in an expanded load range. A reliability assessment of the operation of components of the steam-and-water and air-gas paths, the feed-water pump group, and the draught equipment was conducted.
