Abstract
Periodic test can check the time of valve opening and closing, and prevent valve jamming, which impacts the safety and economy of nuclear-power plant directly. For solving the problem of the greater load fluctuation, the control principle of the steam control-valve and the scheme of the valve periodic test are researched. The reason of greater load fluctuation is analysed. An optimization of valve control strategy is provided and introduced. Finally the optimization scheme is verified during field valve test. The field test result indicates that load fluctuation has been greatly reduced during valve periodic test and the total valve test time is greatly shortened, so the nuclear power plant can return to rated power ahead of time. The optimization greatly enhances the safety and economy of nuclear power plant. The optimization scheme mentioned can also provide reference for other turbine units.
