    摘 要:傳統放射型柔性多狀態開關 (SOP) 直流母線一旦故障會導致整個裝置失效。提出了環網型 SOP 的接入方式,來解決直流側故障問題,還能在控製各端口間功率傳輸的同時,實現無功補償、諧波抑製和三相不平衡抑製等電能質量調節作用。對環網型三端口 SOP 數學模型和控製方式進行了分析,設計了各端口在不同控製模式下的控製器,並用混成切換控製理論設計了環網型三端口 SOP 的控製策略,使其能很好地實現故障恢複以及電能質量調節作用。在 MATLAB/Simulink 中搭建仿真模型,仿真結果驗證了所提方案的有效性和可行性。

    Abstract: The entire device will fail if the traditional radial SOP DC bus fails. This paper proposed a way of access of ring network type SOP to solve the problem of DC fault. It could control the power transmission between ports and play a role in power quality regulation, such as achieving reactive power compensation, harmonic suppression, three-phase imbalance suppression. This research analyzed the mathematical model and control mode of ring network three-port type SOP and designed the controller of each port in different control modes. Moreover,it created the control strategy of ring network three-port type SOP by using the theory of hybrid switching control and helped achieve better fault recovery and power quality regulation. A simulation model was constructed in MATLAB/Simulink, and the simulation results verified the effectiveness and feasibility of the proposed solution.
    Key words: flexible multi-state switch; flexible interconnection; trend control; ring network type; hybrid switching control
