The influence of single valve control and sequence valve control for high-pressure valve of CC50 double extraction steam turbines on such indices as the extraction parameters of each section
inner efficiency and electric energy production were studied by calculation.The results showed that
compared with the single valve control
the unit under sequence valve control had lower extraction temperature
obviously at the first to third stage extraction.The inner efficiency of the first extraction stage and the whole turbine was increased by 7.56% and 0.46%
respectively.The unit electric energy production had a growth of 0.74 MW.
