摘要
在交流配电网基础上建设交/直流混合配电网是未来电网发展趋势,但分布式电源、储能装置等直流设备接入对传统交流配电网的运行产生巨大影响。通过分析交/直流混合配电网中柔性直流控制装置的不同运行模式以及引起控制装置闭锁的故障类型,提炼总结柔性直流控制装置可能存在的闭锁条件,为交/直流配电网的优化运行提供指导建议。
Building AC-DC hybrid distribution network on the basis of AC distribution network is the future development trend of power grid,but the access of DC equipment such as distributed power supply and energy storage devices has a huge impact on the operation of traditional AC distribution network.This paper analyzed the different operation modes of the flexible DC control device in AC-DC hybrid distribution network and the fault types that causes the blocking of the control device,summarized the possible blocking conditions of the flexible DC control device,which can provide guidance and suggestions for the optimal operation of the AC-DC distribution network.
