| 摘 要： | 鲁西背靠背直流与观音岩直流工程是云南电网与南方电网主网异步联网的依托工程,分析了因两回直流逆变侧均为弱交流系统,且两回直流之间电气距离较近,存在交流故障导致直流不够稳定,以及无功小组容量偏小等问题。提出了加强交流系统、控制直流之间的电气距离、加装动态无功补偿装置、采用柔性直流与常规直流组合并利用柔性直流提供动态无功补偿等的综合解决方案,电磁暂态仿真证明了该综合方案的有效性。

| Abstract: | Luxi Back-to-back HVDC project and Guanyinyan HVDC project are the supportive projects for asynchronous interconnection between Yunnan Power Grid and the main grid of China Southern Power Grid(CSG).Some issues are analyzed that due to the inverter sides of these two projects terminate in weak AC system and the electrical distance between the two HVDC projects is relatively short, the HVDC system maybe unstable when AC system fails, and the reactive power compensation capacities is not sufficient A series of integrated solutions are proposed including strengthening the AC system, increasing the electrical distance between the HVDC systems, installation of dynamic reactive power compensation devices, combined application of VSC HVDC and regular HVDC and providing dynamic reactive power compensation support by VSC HVDC.The solutions are proved effective by electromagnetic transient simulation |
