Abstract：Based on engineering application and design examples of flexible HVDC in project, topology structure,working principle and control strategy design of HVDC system are analyzed. Plus-minus DC bus bipolar power supply mode of flexible HVDC transmission system is designed. System can safely switch between the bipolar and unipolar mode. It can be charged repair in single-pole fault. The reliability of system operation is improved. By the control system, power module design and demonstration of HVDC flexible technology in offshore platform, a solid foundation has been laid for the application of island multi-terminal HVDC system.
