        摘 要:柔性直流技術應用于配電網可提高配電網的可靠性和靈活性。結合蘇州工業園區兩端口柔性直流互聯的交直流混合配電網,分析了該區域在正常和故障情況下的運行控制策略。正常情況下,采用集中-分區的控制層級模式,利用柔性直流的運行特性和微電網控制技術,支撐新能源消納、重載風險消除等多個場景。故障情況下,基于柔性直流帶無源負荷的供電能力分析模型,通過配網主站系統、柔性直流控制系統和保護裝置的協同配合,實現配電網故障的快速處置。

        Abstract: The application of flexible DC technology is able to increase reliability and flexibility of distribution network. The paper, taking the AC/DC hybrid distribution network with two-port flexible DC interconnection in Suzhou Industrial Park as research object, makes analysis of its operational control strategy under normal and fault conditions. When the distribution network runs normally, the centralized-partition control mode is adopted. The operating characteristics of flexible DC technology and micro-grid control technology are used to support multiple scenarios, such as new energy accommodation and heavy load risk elimination. When faults occur in the distribution network, the main station system, flexible DC control system and protection device are controlled in a coordinated way to fast deal with faults based on the power supply capability analytical model of flexible DC with passive load.
        Key words: flexible DC; distribution network; coordinated control; fault disposal
