以某船用汽轮机发电机组为研究对象，对其控制原理进行理论分析与推导，建立其控制系统的数学模型，并在SIMULINK平台上完成了常规法甩负荷50%与100%仿真实验，得到两组响应曲线。分析结果表明：该控制系统能够实现机组的甩负荷工况转速控制，在负荷骤降的情况下可以保证机组安全稳定运行。

Taking a certain marine steam turbine generator unit as the research object,the theoretical analysis and derivation to its control principle were conducted,a mathematical model of its control system was established,and 50% and 100% load rejection simulation tests on the SIMULINK platform by the conventional method were completed to obtain two sets of response curves.The analysis results show that the control system can accomplish the speed control of the unit under the load rejection condition,which can ensure the safe and stable operation of the unit in the case of a sudden load drop.
