| 摘要: |
| 在建立基于等效电路的超级电容器储能（SCES）系统的数学模型基础上，设计了一种超级电容器储能的动态电压恢复器（DVR）。该DVR以超级电容器为直流侧储能单元，采用非隔离型Buck-Boost双向DC／DC变换器进行双闭环功率前馈控制，采用双向电压源型DC／AC变换器进行解耦和前馈补偿控制。根据SCES的特性，确定了系统的基本运行原理，即当电源电压暂降时，通过调节DVR输出的有功功率和无功功率来维持负载电压幅值和相位的稳定。仿真实验结果验证了该DVR拓扑结构及其控制策略的正确性和有效性。 |

| Abstract: |
| The mathematical models of SCES（Super Capacitor Energy Storage） system are built based on the equivalent circuits and a kind of DVR（Dynamic Voltage Restorer） based on SCES is designed，which uses the super capacitor as the storage component at its DC side，applies the non-isolated Buck-Boost bi-directional DC／DC converter in its double closed-loop power feed-forward control and adopts the bi-directional voltage-source DC／AC converter in its decoupling and feed-forward compensation control. Its operating principle is established according to the characteristics of SCES，which regulates the active and reactive powers of DC/AC converter to stabilize the load voltage when the source voltage drops. The correctness and effectiveness of the designed DVR are verified by simulation and experiment. |
