| 摘要: |
| 首先分析了系统在交直流并列运行和孤岛运行方式下的控制策略，基于此提出了系统从交直流并列运行转为孤岛运行和从孤岛运行恢复到交直流并列运行的切换控制方法。以某实际工程参数为例在PSCAD／EMTDC仿真平台上搭建了系统仿真模型，对所提出的切换控制方法进行了仿真验证。结果表明，所设计的切换控制方法能及时检测出系统的运行状态，并自动进行相关控制方式的切换，在切换过程中系统各电气量没有剧烈波动，不会影响系统的安全稳定运行。 |

| Abstract: |
| The control strategy of VSC-HVDC transmission system is analyzed respectively in AC-DC parallel operating mode and islanded operating mode，based on which，the strategy of mode switching control is pro-posed. Based on the parameters of an actual project，a system simulation model is established on PSCAD／EMTDC platform and the proposed control strategy is verified by simulation. Results show that，it detects the operating conditions of VSC-HVDC transmission system timely and switches the corresponding control strategy automatically. The electrical parameter fluctuation during mode switching is slight and the stable system operation is not affected. |
