摘要：对大型船舶，尤其是大型水面舰艇而言，汽轮发电机组是其电网中不可或缺的组成部分，而我国20世纪引进的以汽轮发电机组供电的大型船舶中，许多汽轮发电机组的电气部分已严重老化，导致故障频发。同时，原有监控装置采用的是由分立元件组成的模拟式电气液压控制器，可靠性和可维修性差。针对上述间题，依托某型船汽轮发电机组改换装项目，对汽轮发电机组控制设备的改装进行研究。设计新型数字式电气液压控制器，实现对原有控制器的整体替换。为验证新研控制器的性能和可靠性，研究改装汽轮发电机组的模型，建立硬件在环实时伤
真系统。仿真结果表明，新研控制器可很好地实现对汽轮发电机组的控制功能。关键词：船舶汽轮发电机数字式电气液压控制；硬件在环

Abstract: For large ships, especially for large naval vessels, steam turbine generator set is one of the fundamental components of the ship power system. Last century, a large number of turbine-generator set were imported to China. Because of years of service, seriously ageing of electrical parts of these turbine-generator sets leads to frequent malfunctions, Because the original monitoring system uses analog electrie-hydraulic design with discrete components, its reliability and maintainability is poor. To solve the problems, a new digital electro-hydraulic controller for replacing the original analogue controller is developed as a part of the power station modification project for one of the imported ships. In order to verify the performance and reliability of the new controller, a mathematic model of the steam turbine generator set is built, and a hardware-in-the-loop real-time simulation system is constructed. The simulation results show that the newly developed controller can well achieve the control function of the steam turbine generator set.

蒸汽轮机具有单机功率大、寿命长、可靠性高、重量轻、尺寸小、经济性较好、可用廉价燃料及维护简单等优点，因此在大型船舶（尤其是大型水面舰艇)电力系统领域，汽轮发电机组得到了十分广泛的应用。我国在 20世纪引进了较多大型船舶，其中有相当一部分的船舶电力系统均采用汽轮发电机组。由于使用时间较
