【 摘 要 】

The mixed-valve sequence of an ultra-supercritical steam turbine designed by the manufacturer is only applicable to basic load. The best initial steam pressure corresponding to the different load under the sequence-valve sequence is determined by field optimization test, which can improve the operating economy and the frequency-modulation response capability under partial load.
