电力系统机电-电磁暂态混合仿真接口技术

在电力系统仿真中，相互独立的机电暂态程序与电磁暂态程序由于各自的不足和局限，已经难以适应快速发展的现代电力系统对仿真技术的要求；如果能在一次仿真过程中同时实现大规模电网的机电暂态仿真与部分电网的详细电磁暂态仿真，那么对详细分析系统特性具有重要的理论价值和现实意义。文章对该技术进行了研究，认为接口的处理是其中的关键，在此基础上重点阐述了接口位置选择、等值电路形式、数据交互方式以及数据转换等核心问题，并在实时数字仿真系统-RTDS平台下初步实现该技术。

Technology of Interfaces for Hybrid Simulation of Power System Electromagnetic-electromechanical Transient Process

Due to respective disadvantage and limitation of mutual independent electromechanical transient simulators and electromagnetic transient simulators, it is difficult for these simulators to meet the need of rapidly developing modem power grids in simulation technology. This paper researched this technology and considered that the processing of interface is the key problem in hybrid simulation. On this basis, the kernel issues such as selection of interface location, mode ofequivalent circuit, interactive mode ofdata and data conversion were emphatically expounded. And the relative technology was primarily implemented under the real-time simulation system-RTDS platform.
