| 摘要: |
| 张北柔性直流电网示范工程(简称张北工程)将建成世界上首个柔性输电直流电网。不同于以往的多端直流工程，张北工程采用直流断路器对线路故障进行隔离。四端口字型网架结构为潮流提供迂回和备用通道，极大地提高了工程运行的灵活性和可靠性，形成了真正意义上的直流电网。根据张北工程各个换流站所连接交流系统的特点，研究并提出了针对该工程的控制系统架构和协调控制的相关功能，以及有无站间通信方式下具体的控制策略。通过闭环RTDS实时仿真验证了该策略的可行性和合理性。 |

| Abstract: |
| Zhangbei Demonstration Project (namely Zhangbei Project) will be the first MMC-HVDC grid in the world. Different from previous multi-terminal HVDC projects, DC circuit breakers are adopted in this project to isolate DC line faults. Four terminal ring connection of converters can provide circuitous and standby channels for power flow. This improves the flexibility and reliability of operation of the project greatly and forms the real MMC-HVDC grid. Based on the characteristics of different AC systems connecting to each converter in the Zhangbei Project, the related functions of the control system structure and coordination control for this project are studied and proposed. Corresponding control strategies with and without inter-station communication conditions are proposed. The feasibility and rationality of the control strategy are verified by closed-loop RTDS simulation.
