摘　　要：考虑核电站汽轮机所具有的水膜闪蒸和水膜与壁面换热后，核电汽轮机动态模型和常规火电机组的差别仅在于容积方程。研究表明，两者的差别在于核电汽轮机动态模型中的容积方程增加了水膜蓄热和壁面蓄热两项传递函数。文中给出了核电汽轮机的容积方程。Considering the water film flash vaporization and the heat exchange between water film and solid surface,volume equation has difference for nuclear power steam turbine dynamic modle and routine unit.Study show that volume equation of nuclear power steam turbine dynamic modle increased water film and wall stored heat.Volume equation of nuclear power steam turbine is presented in this paper.
