摘　　要：从现行的消磁脉冲电流对发电机组转速产生较大影响的事实出发,研究机组运行情况的数学模型,建立了基于Matlab的系统框图模型,并进行仿真实验,实验结果定量描述了消磁脉冲电流对机组转速影响的程度。在此基础上,提出了使用上升沿较缓的电流波形的方案。仿真结果表明,该方案可行。Based on the bad influence of the actual degaussing current on the rotate speed of diesel generator set and the normal working state, this paper studied the mathematic model of the generator set. According to the synthetical degaussing, a frame modal was established on the base of Matlab/ Simulink before emulational experiment. The experiment result reveals the degree of the bad influence. And then, two new current waveforms whose risetime were longer than that of the actual waveform were preseated. The simulation shows that the project is feasible.
