| 摘 要： | 提出了一种适用于多端柔性直流输电系统的协调控制策略。在协调控制中采用分段系数电压斜率控制,提高了直流网络在发生不同程度的功率变化时的运行稳定性;在换流站本地控制中采用无差拍直接功率控制,提高了功率响应的速度和控制精度。最后通过Matlab/Simulink建立多端柔性直流输电系统的仿真模型,验证了策略的有效性。

| Abstract: | A novel synergy control scheme was proposed for the voltage source converter multi-terminal high voltage DC transmission （ VSC-MTDC ） system. The partition coefficient voltage slope control can improve the operation reliability of the VSC-MTDC and the direct power control can help with the dynamic response speed and precision of the converter station. The simulation results show that the control strategy is effective. |
