向家坝-上海±800 kV特高压直流在失去与四川主网全部500 kV联络线后,将进入孤岛运行.为此,讨论了向-上直流进入孤岛和孤岛运行两种运行方式下的控制策略,提出了孤岛运行对某些的交换功率限制,以及孤岛运行时的通信系统配置和频率控制器模型及参数.对进入孤岛及孤岛运行时的多种故障的仿真表明,在设计的频率控制器作用下,向-上直流可以保持稳定运行.
嚮傢壩-上海±800 kV特高壓直流在失去與四川主網全部500 kV聯絡線後,將進入孤島運行.為此,討論瞭嚮-上直流進入孤島和孤島運行兩種運行方式下的控製策略,提齣瞭孤島運行對某些的交換功率限製,以及孤島運行時的通信繫統配置和頻率控製器模型及參數.對進入孤島及孤島運行時的多種故障的倣真錶明,在設計的頻率控製器作用下,嚮-上直流可以保持穩定運行.

In accordance with the Xiangjiaba-Shanghai UHVDC(XS800)island operation-2 different control strategies were discussed for entering island mode and island mode operation.Power exchange limits under some scenarios as well as communication and frequency control model and parameters were proposed.Simulation on the fault cases indicate that the XS800 UHVDC system can maintain stable operation with the help of designed frequency control block.
