| 摘要: |
| 从用于超级电容器（UC）储能系统功率调节的电压源型变流器（VSC）的时域数学模型出发，基于交流侧电流两相旋转坐标系的解耦控制，研究了用于提高超级电容器储能系统功率跟踪动态特性的实时功率控制策略。同时设计了用于连接UC和VSC接口的DC／DC变换器，在此基础上实现了通过超级电容器充放电补偿变流器直流侧电压变化控制策略。仿真结果表明所研究的功率调节方法能够在四象限内进行超级电容器有功、无功功率的快速解耦控制，同时验证了所研究的实时功率控制策略的正确性和可行性。 |

| Abstract: |
| According to the mathematical model of voltage source converter，the real-time power control is studied to enhance the dynamic power tracking characteristics of UC（UltraCapacitor） energy storage system based on the decoupling control of AC-side currents under d-q synchronous reference frame. The DC-DC converter for connecting UC with the voltage source converter is designed and the control strategy for compensating DC voltage variation by UC charge／discharge is realized. Simulative results show that，the proposed power control system carries out effectively and rapidly the decoupled control of active power and reactive power in four quadrants，verifying the validity and feasibility of the proposed control strategy. |
