【 摘 要 】

Zhou Shan voltage source converter multi-terminal HVDC system (VSC-MTDC) enhances the receptiveness of wind power and improves the reliability of power supply. Electrical energy transfers flexibly between the islands in Zhou Shan. Restricted by the half-bridge sub module and disconnector, Zhou Shan VSC-MTDC cannot realies fast DC fault recovery. In order to solve this problem, damping fast recovery system and DC breaker are added. Meanwhile, the corresponding control strategy is proposed. It is verified by experimental results that the control strategy will realise fast DC fault recovery and improve the reliability of Zhou Shan VSC-MTDC dramatically.
