| 摘 要： | 传统的机电暂态仿真对电力电子装置例如HVDC和FACTS采用准稳态模型,因而不能仿真动态过程中电压、电流的变化.而电磁暂态仿真程序（例如EMTP,EMTDC）受计算规模的限制,一般要对研究对象的外部电力系统进行等值化简,因此,不能反映系统机电暂态过程对电磁暂态过程的影响.该文中的混合仿真算法为弥补上述两种方法的不足,对电力网络采用准稳态模型,而对待研究的电力电子装置使用电磁暂态模型,EMTP仿真中考虑了频率偏移对电磁暂态仿真的影响.混合仿真算法为研究各种FACTS电力电子装置及其控制系统的动态性能提供了一种实用的工具.

| Abstract: | In power system simulation, since the quasi steady state models for HVDC and other FACTS electronic devices are usually adopted for transient stability study, their rapidly transient responses both in voltages and currents cannot be simulated in detail. On the other hand, limited with the capability of electromagnetic transient simulation approach, the outside power system is usually represented by a reduced equivalent system model while performing simulation using commercial EMTP software. The hybrid simulation algorithm presented in this paper simulates the pre -selected power electronic devices and in the same time simulates the outside AC power system with traditional transient simulation method. The hybrid algorithm proposed in this paper can provide a useful tool for studying dynamic performance of FACTS devices. |
