摘要(Abstract)：

火电直流孤岛送出系统有效短路比和转动惯量小,孤岛送出系统承受扰动能力较弱,频率稳定问题突出,给含大量热力生产过程的火电直流孤岛运行方式决策带来了巨大的困难。建立了准确反映伊穆直流系统、火电机组实际特性的电磁暂态仿真模型,通过仿真分析,提出了伊穆直流孤岛试验条件和控制策略;对拟开展试验项目提供了操作建议并进行了详细仿真,为世界首次进行的火电直流孤岛运行特性试验方案制定和实施提供了坚实的工作支撑;现场试验结果验证了系统分析与电磁暂态模型的有效性,为开展后续研究工作奠定了基础,为未来大型火电基地的集中开发和远距离外送提供了技术依据。

关键词(KeyWords)： 火电直流孤岛运行;电磁暂态仿真;附加频率控制;一次调频
