摘　　要：针对小型工业汽轮机功率小、控制相对简单的特点,选用独立的调速控制器或过程控制系统作为对其控制的核心,并在此基础上,对小型工业汽轮机的机械监测系统、超速保护系统、调速系统的使用情况分别进行了总结分析。结果表明,该系统能够改善小型汽轮机的控制质量、灵敏性,提高了执行机构响应速度,降低了机组运行成本。In view of the characteristics of small industrial steam turbines with low power and relatively simple control,an independent speed controller or process control system is selected as the core of its control,and on this basis,the mechanical monitoring system,overspeed protection system,and the use of the speed control system were summarized and analyzed.The results show that the system can improve the control quality and sensitivity of the small steam turbine,improve the response speed of the actuator,and reduce the operating cost of the unit.
