摘　　要：基于轻型直流输电(HVDC Light)在海上油气田的运用实例,分析设计了轻型直流输电系统的拓扑结构,阐述了其工作原理和控制策略。系统采用正负直流母线双极供电模式,系统可在"双极模式"与"单极模式"之间安全切换,且发生"单极故障"可带电维修,大大提高系统了系统运行的可靠性。最后应用Matlab仿真软件搭建了系统的Simulink仿真模型,仿真结果验证了系统设计的正确性与可行性,为轻型直流输电技术在海上油气田的应用奠定了坚实基础。On the basis of the application of HVDC Light in the offshore oil, this article designs the structure of the HVDC Light system and describs the principle and the control strategy. In order to improve the reliability, the bipolar power supply mode of the positive and negative DC bus was adopted. The system achieved the switch between the bipolar mode and the unipolar mode and charged maintenance. Matlab simulation software set up the simulation model of this system, the simulation result proved the correctness and feasibility of the design. The design of this system laid a solid foundation for the application of HVDC-Light in offshore oil platform feilds.
