基于数字计算机和RTDS的实时混合仿真

Digital Computer and RTDS Based Real-time Hybrid Simulation

阐述了计算机机电暂态仿真、RTDS电磁暂态仿真的实时混合仿真平台设计思想,给出了整体设计架构,详细分析和阐述了两侧接口数据交互和同步协调仿真流程、混合仿真接口方案以及接口数据传输方法等关键技术。以含南方电网贵广高压直流的简单交直流系统算例研究验证了该混合仿真平台的设计和实现是可行的、有效的。

This paper presents a novel hybrid simulator, in which the digital computer and RTDS carry out the electromechanical and electromagnetic transient simulation, respectively. The overall design is proposed and the key techniques are studied in detail, including the interaction process between the two sides and the flow of synchronous simulation, the interface scheme for hybrid simulation, and the method for interface data exchange. A case study of the actual AC and DC hybrid power system containing the Gui-Guang HVDC system of China Southern Power Grid testifies to the practicability and validity of the overall design and the implementation of the hybrid simulator.
