电力系统电磁暂态-机电暂态混合仿真的应用

作者在关于电力系统电磁暂态-机电暂态混合仿真研究的系列报告的前两篇中曾提出了一种混合仿真的通用接口方法以及相关实现算法。在该混合仿真研究的系列报告之三中, 作者主要检验了系列报告一、二中提出的接口模型、接口算法在实际电力系统中的应用效果,包括:IEEE 14节点系统故障后的仿真分析、东北-华北-华中-川渝联网系统中伊敏-冯屯线路安装固定串补后系统次同步谐振的时域分析。仿真结果证明了作者提出的混合仿真的接口方法和模型的有效性与实用性。

Application of Hybrid Simulation of Power System Electromagnetic-Electromechanical Transient Process

The authors have proposed a general interface method and its related algorithm for hybrid simulation of power system electromagnetic transient and electromechanical transient processes in the first two of serial papers about hybrid simulation. Here, in the last one of these serial papers, to verify the application results of the interface model and interface algorithm proposed in previous two papers, the simulation analysis results of post-fault IEEE 14-bus test system and time-domain analysis results of sub-synchronous resonance occurred in Yimin-Fengtun transmission line with fixed series capacitor, which is a part of practical interconnected power grids consisting of Northeast China power system, North China power system, Central China power system and Chuanyu power system, are presented. These results show that the proposed interface algorithm and model are practicable and effective.
