摘要(Abstract)：

为满足未来更大容量、更远距离的输电需求,有必要进一步研究更高电压等级的直流输电技术,±1100 kV直流是我国正在研究的一个全新输电电压等级,对于提高我国直流输电技术的自主创新能力具有重大意义。基于2020年规划电网,在对原网进行等值的基础上,在电磁暂态程序上建立交直流系统研究模型,研究了送/受端交流系统故障、直流系统故障对交直流系统运行特性的影响,提出±1100 kV直流输电系统控制保护参数及配置的需求和优化措施,研究结果可为±1100 kV直流输电工程提供技术参考。

关键词(KeyWords)： PSCAD/EMTDC;±1100 kV;接入系统;直流控制保护;换相失败
