		    摘 要：傳統(tǒng)放射型柔性多狀態(tài)開關 (SOP) 直流母線一旦故障會導致整個裝置失效。提出了環(huán)網(wǎng)型 SOP 的接入方式，來解決直流側故障問題，還能在控制各端口間功率傳輸?shù)耐瑫r，實現(xiàn)無功補償、諧波抑制和三相不平衡抑制等電能質量調節(jié)作用。對環(huán)網(wǎng)型三端口 SOP 數(shù)學模型和控制方式進行了分析，設計了各端口在不同控制模式下的控制器，并用混成切換控制理論設計了環(huán)網(wǎng)型三端口 SOP 的控制策略，使其能很好地實現(xiàn)故障恢復以及電能質量調節(jié)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.
