摘　　要：现代武器装备越来越多的呈现出冲击特性,给柴油发电机组的安全稳定运行造成了严重影响。冲击性负载的冲击特性受到负载功率大小、工作原理等的影响,以柴油发电机组带电动机和脉冲性负载为对象,在Matlab/Simulink仿真平台上,建立柴油发电机组-冲击性负载模型,对不同工作原理冲击性负载下柴油发电机组运行状况进行检测,根据检测结果分析柴油发电机组输出频率和电压的瞬态和稳态指标,并对各项指标作出对比。结果表明,不同工作原理的冲击性负载作用下,相同功率的容性负载和感性负载作用于柴油发电机组,引起柴油发电机组输出频率幅值变化范围与电压的升高和跌落都存在着差异。在对柴油发电机运行特性改善中,应充分考虑冲击性负载工作原理,以采取正确的改善措施。More and more modem weapons and equipment show the impact characteristics, which has a serious impact on the safe and stable operation of diesel generator sets. The impact characteristics of the impact load are af- fected by the load power and working principle. On Matlab/Simulink simulation platform, taking diesel generator sets with the motor and the pulse load as the object, the diesel generator set - impact load model was established. The op- eration condition of diesel generator set under different working principle was studied. According to the test results, the transient and steady state indexes of the output frequency and voltage of diesel generator sets were analyzed and compared. The results show that with the impact loads based on different working principles, the capacitive load and inductive load with the same power and acting on diesel generator, can cause different increases and drops of diesel generator output frequency range and amplitude of voltage. In order to improve the performance of diesel generator, the principle of impact load should be taken into account in order to take correct measures.
