摘　　要：陆战平台全电化发展使得电传动履带车辆源-网-荷拓扑的电力电子化程度不断加深.以电传动履带车辆为研究对象,聚焦电气系统源-网-荷暂态特性,通过分析电力电子变换装置时变拓扑、多时间尺度控制、强非线性、弱抗扰性、结构复杂等特征,结合车辆载荷特征,建立了复合能源供电下的系统模型.提出平均状态空间小信号分析结合基于非线性解耦的大信号分析来分析系统的暂态稳定性,并通过系统仿真验证所建立模型和所提出分析方法的有效性、准确性.With the development of the all-electric land warfare platform, power electronics have increasingly dominated the source-network-load topology for electric tracked vehicles. This paper focuses on the transient characteristics of the source-network-load electricalsystem for electrically driven tracked vehicles. The time-varying topology, multi-time scale control, strong nonlinearity, weakdisturbance rejection, and complex structure of power electronic conversion devices and the vehicle load characteristics are analyzed,and a system model under composite energy supply is established. An average state-space small signal analysis method combinedwith large signal analysis based on nonlinear decoupling is adopted to analyze the system transient stability. Finally, the effectivenessand accuracy of the established model and the proposed analysis method are verified via simulation.
