摘要
根据船用汽轮机的热力学原理与汽轮机功率模型,设计一种基于常规PID的船用汽轮机功频控制系统,并运用Matlab/Simulink仿真模块对其进行仿真计算。结果表明,当二回路负荷发生变化时,该控制系统可通过调节汽轮机的进汽量,使汽轮机的功率能够快速跟踪发电机功率的变化,并维持汽轮机的转速(频率)不变。
A power-frequency governing system of marine steam turbine based on PID was designed,according to the thermodynamics principle and the power model of the marine steam turbine.Matlab/Simulink was introduced to perform the simulation.The results show that the governing system responds quickly with the power change of generator.By regulating the steam flux into steam turbine,the system keeps the rotatary speed（frequency） relatively constant,while the steam load disturbs in the secondary circuit.
