摘　　要：设计了一种基于超级电容器储能系统的动态电压调节器,该调节器以超级电容器为直流侧储能单元,采用双向电压型DC/AC变换器进行解耦和前馈补偿控制,采用半桥式电压型双向DC/DC变换器进行双闭环反馈控制。仿真结果验证了该调节器拓扑结构及其控制策略的正确性和有效性。To solve voltage sag, voltage swell and three phase voltage unsymmetry, a mathematical model of ultrlacapacitor energy storage system based on equivalent circuit is built and a kind of dynamic voltage conditioner （DVC） based on ultracapacitor energy storage is designed. Using ultracapacitor as the energy storage component at DC side of the DVC, the decoupling and feed forward compensation control of the DVC are implemented by bi-directional voltage source DC/AC converter and the duplicate closed-loop feedback control of the DVC is implemented by half-bridge bi-directional voltage source DC/DC converter. The correctness and effectiveness of the topological structure of the DVC and its control strategy are verified by simulation results.
