| 摘 要： | 基于实时数字仿真器（RTDS），针对实际的交直流混合电网，搭建了仿真模型，并将RTDS与实际直流输电控制保护装置连接，建立了一个交直流混合系统实时仿真实验平台。介绍了仿真建模中的关键问题，提出了RTDS元件模型的选择原则。在此基础上，对南方电网中实际发生的 2种典型故障进行了仿真研究，通过仿真实验成功再现了实际故障过程，并分析得出了故障发生的真实原因，提出了合理的改进建议。通过仿真结果与实际录波的对比，证明所建电网模型是准确、可信的，能够比较真实地反映实际系统的动态特性。

| Abstract: | An AC-DC real-time simulation system is developed,in which an equivalent model of China's southern power grid is built on a real-time digital simulator(RTDS),while the external actual DC control and protection devices are connected in a closed loop.The key problems in modeling are discussed and suggestions are made to improve the RTDS model.Two typical actual faults have been successfully simulated by use of the RTDS model.The real causes of faults are analyzed,and some improvement measures are put forward.... |
