Cycles of steam turbine plants are considered at high values of initial pressure of vapor and pressure of intermediate superheat and deep vacuum in condenser. It is shown, that at such conditions the degree of dryness of vapor at the end of extension in the low-pressure turbine shall be less than the limit admissible value. To exclude this phenomenon it is necessary at deep vacuum in condenser to use the second intermediate superheat of vapor.
