摘要
电力电子化电力系统具有一定的特殊性,当电力电子器件的开关在进行动作的过程中其拓扑结构也相应地会发生变化,而且电力电子化电力系统本身具有较强的非线性,系统的整体结构非常复杂,状态变量的阶数也相对比较高,由于上述原因导致电力电子化电力系统的暂态稳定性也面临着巨大的考验.本文主要针对电力电子化电力系统的基本结构特征进行了深入分析,并在此基础上对电力电子系统暂态稳定性进行了深入研究.
The power electronic power system has certain peculiarities.When the switch of the power electronic device is in the process of action,its topology will change accordingly,and the power electronic power system itself has strong nonlinearity.Moreover,the overall structure of the system is very complicated,and the order of the state variables is relatively high.Due to the above reasons,the transient stability of the power electronic power system is also facing a huge test.In this paper,the basic structural characteristics of power electronic power system are analyzed in depth,and the transient stability of power electronic system is also studied in depth.
