论文介绍了VSC-HVDC与传统HVDC相比的优点。然后提出了开发大容量电网用直流断路器的必要性和挑战。还介绍了不同类型直流断路器的基本工作原理。最后对直流断路器在舟山柔性直流输电工程中的应用进行了阐述。上述策略大大提高了柔性直流输电工程的可靠性，实现了直流输电系统出现故障时的快速隔离。这是全球首个应用于VSC-HVDC项目的直流断路器，具有重要意义。
The advantages of VSC-HVDC compared with the traditional HVDC are introduced in the thesis. Then the necessity and challenges of developing DC circuit breaker used in large-capacity power grid is proposed. Basic operation principles of different types DC circuit breaker are described as well. At last, the application of DC circuit breaker in Zhoushan flexible HVDC project is illustrated. The strategy above has greatly improved the reliability of flexible HVDC project and achieved rapid isolation when the HVDC system come to a failure. It is the first DC circuit breaker used in VSC-HVDC project around the world and has great significance.
