摘　　要：在汽轮机带负荷运行中,回热器如同再热器一样对汽轮机的负荷响应特性有延滞效应,但传统的汽轮机模型对此未加考虑;该文基于机理建模思想导出了一个新的汽轮机动态模型,并讨论了给水回热系统动态蓄热效应对汽轮机的动态特性的影响。Regenerators will delay the load respond speed of turbine as reheaters when turbines run with load. But all of the turbine models do not take into account of the effect of regenerators. A new dynamic turbine model has been developed with the idea of modeling by mechanism in this paper, and the influence of the dynamic thermal storage of regenerator on turbine dynamic characteristics has been discussed.
