摘　　要：将汽轮机的调节系统框图,逐一拆解成各数学模型进行研究。利用传递函数的特性及劳斯-赫尔维茨稳定判据来分析汽轮机的动态特性。调整其中主要的四个参数,不等率δ、油动机时间常数Tμ、蒸汽容积时间常数Tρ与转子时间常数Tα等,考察对其稳定性的影响。仿真结果与理论分析相吻合。This paper disconnects an adjustment block-diagram of steam turbine into several mathematical model to research. By using characteristics of transfer function and Routh-Hurwitz criterion, it analyzes steam turbine dynamic characteristics. By regulating four major parameters such as diversity factor δ, time constant of oil motor Tμ, vapor volume Tρ and rotor Tα, it researches its effect on stability. The results of simulations show that it is in a good agreement with that of theories.
