摘　　要：含有DC/DC开关电源的脉冲负载在船舶上得到广泛应用,脉冲负载建模是研究含脉冲负载船舶电力系统稳定性的前提。根据脉冲负载的周期波动特点,提出了RL脉冲负载等效方式。在分析脉冲负载导通过程的基础上,提出了含有双时间尺度脉冲负载的状态方程建模方法。仿真结果表明本文所提的状态方程具有一定的正确性,能够较好的反应脉冲负载的动态过程。本文的研究结果对脉冲负载参数及稳定性分析研究具有重要参考价值。Pulse loads containing DC/DC switching power supplies have been widely used on ships.Pulse load modeling is the prerequisite for studying the stability of ship power systems with pulse loads.According to the periodic fluctuation characteristics of the pulse load,the RL pulse load equivalent method is proposed.Based on the analysis of pulse load switching-on process,a modeling method of state equation with dual time scale pulse load is proposed.The simulation results show that the state equation proposed in this paper has a certain degree of accuracy and can reflect well the dynamic process of pulse load.The research results introduced in this paper have important reference value for the pulse load parameters and stability analysis.
