| 摘 要： | 未来多个直流输电系统落点于上海地区,将构成多馈入直流输电系统.以2010年上海电网规划数据以及届时落点于上海电网的葛洲坝-南桥、三峡-上海华新2条直流输电系统为仿真研究对象,主要研究了当直流输电系统出现故障时对上海电网的暂态稳定带来的影响.仿真结果表明:当南桥、华新换流站发生直流输电单双极闭锁以及交、直流侧短路故障时,不会给系统带来稳定问题.

| Abstract: | In future,several HVDC systems will set in Shanghai,which is expected to create a multi-infeed HVDC system.Based on the data on 2010 Shanghai Grid plan,and taking the two HVDC systems,Gezhouba to Nanqiao and Three Gorge to Shanghai Huaxin,which will have set in Shanghai by 2010 as simulation objects,the impacts of multi-infeed HVDC system faults on transient stability of Shanghai Power Grids are studied.The results show that occurrence of the single or double pole block on the DC lines,or short-circuit faults on the DC or AC lines will not influence seriously on power system stability. |
