摘要
储能系统作为电力系统必要的能量缓冲环节,作用非常明显。使用双电层电容器(electric double layer capacitor,EDLC)的储能系统能够同时控制有功功率和无功功率,因此它能补偿功率波动。提出了电流源超级电容器储能系统(current-source energy capacitor system,CS-ECS)。该系统由双电层电容器、双向直流变直流换流器以及电流源逆变器组成。提出了能对有功功率和无功功率进行控制的CS-ECS控制系统,通过对同步发电机系统进行仿真,得出了超级电容器系统能够改善同步发电机系统稳定性能的结论。
As a necessary energy buffer equipment,energy storage system plays evident role in power system.The energy storage system adopting electric double-layer capacitor（EDLC） can control active and reactive power simultaneously,so it can compensate the fluctuation of power.A current-source energy capacitor system（CS-ECS）,which consists of EDLC,bi-directional DC-DC converter and current-source inverter,is proposed,and a CE-CES control system that can control both active and reactive power is given.Through the simulation of synchronous generator system,the conclusion that the operational stability of synchronous generator system can be improved by CS-ECS is obtained.
