摘　　要：高压大容量电力电子装置在国民经济发展中的需求正在日益增大。然而,由于高压大容量电力电子系统往往由多个变换单元组合而成,结构复杂,时间尺度跨度大,呈现出典型的混杂系统特性,现有仿真软件和方法难以实现准确、高效、稳定的仿真。从电力电子系统的混杂特性出发,以10 kV-2 MW电能路由器装置为仿真算例,展示了所提离散状态事件驱动(DSED)仿真方法在高压大容量电力电子装置仿真中的应用,全面评估该方法与其他仿真软件的性能对比。与目前主流仿真软件相比,DSED方法不仅可以同时实现开关器件瞬态过程和系统级动态过程的准确、高效仿真,其仿真速度相较成熟的电力电子仿真软件如PLECS~?还可以提高1 000倍。DSED为高压大容量电力电子混杂系统的优化设计、高效控制和稳定运行提供了有力的仿真工具。Demands for high-voltage high-power converters are increasing rapidly. Nevertheless, due to their complex structures, multi-time scale characteristics and hybridity, it is difficult to realize accurate, efficient and stable simulation of such systems. From a hybrid system perspective, taking a 10 kV 2 MW electric energy router as an example, we present the application of Discrete State Event-Driven(DSED) simulation framework in high-voltage high-power. Compared with commercially available simulation tools, DSED framework can be applied not only to achieve accurate and efficient simulation of both device-level switching transient and system-level dynamic, but also to achieve up to 1 000-fold improvement in simulation speed compared with commercial power electronic simulation software such as PLECS~?,which offers a powerful simulation tool for analysis, design and control of high-voltage high-power converters.
