Electromagnetic and Electromechanical Decoupled Hybrid Simulation with Mixed Interaction Protocol

提出一种使用SOCKET通信搭建的混合仿真通信框架,以实现机电-电磁混合仿真的完全解耦,在此基础上提出一种可自动切换的串并行结合的混合交互时序,以提高混合仿真的精度和速度。以PSCAD及开源的PSAT为例对混合仿真系统的实现进行了详细描述,并在含有SVC的三机九节点系统上做了验证,表明所提出解耦混合仿真方法及所采用的时序交互方式有效,同时得出了普适性结论,即只要仿真程序支持相关的API调用,则所提出的基于通信的仿真框架均可实现。

This paper presents a decoupled power system simulation method for hybrid simulation with SOCKET communication. An interaction protocol is introduced to automatically switch between serial and parallel protocol to make the hybrid simulation faster and more accurate. PSCAD and PSAT are used to test and verify the proposed hybrid simulation method and interaction protocol in the WSCC 9- bus system with SVC. The result of the test shows that the proposed hybrid simulation method and interaction protocol work effectively.
