        摘 要:針對傳統低壓直流配電系統控制面臨的靈活性不足及系統潮流協調控制難度較大等問題,分析了低壓直流系統的拓撲結構及系統要素,設計了低壓直流系統潮流協調控制器實現對系統的運行狀態管理。該裝置通過對系統內關鍵設備運行數據的采集、分析,按照既定策略通過數據通信實現對系統中各設備運行狀態的調控。在某樓宇低壓直流系統內對裝置進行了測試,運行結果表明,該裝置可有效實現低壓直流系統內的設備控制及潮流管理。

        Abstract: Aiming at the problems of insufficient flexibility of traditional low-voltage DC distribution system control and the difficulty of coordinated control of system power flow, the topology structure and system elements of low-voltage DC system were analyzed, and a lowvoltage DC system power flow coordination controller was designed to manage the system's operating status. The device collects and analyzes the operating data of key equipment in the system, and realizes the regulation of the operating status of each device in the system through data communication according to the established strategy. The device was tested in a building's low-voltage DC system, and the operation results show that the device can effectively implement equipment control and power flow management in the low-voltage DC system.
        Key words: DC distribution; power flow; coordinated control
