摘 要: | 在云南电网与南网主网鲁西背靠背直流异步联网工程中,柔性直流与常规直流背靠背系统处于同一换流站内,共享同一站级控制系统。在柔性直流与常规直流的协调控制策略方面,以往工程无可供参考的设计经验。文章从有功协调控制和无功协调控制策略两方面进行了探讨,并给出了部分协调控制策略的仿真实验结果。

Abstract: | In the Yunnan grid and CSG main grid Luxi BtB (Back to Back) HVDC system, VSC (Voltage Sourced Converter) and LCC (Line Commutation Converter) operate in parallel and share the same centralized station control system. Thus the VSC/LCC BtB HVDC coordination control strategy problem is introduced. This paper studies the coordination control strategy from the active and reactive aspects, and gives the partial simulation results of the proposed strategies. |
