| 摘 要： | 文章介绍了链式STATCOM的拓扑结构，在此基础上建立了数学模型。直流侧电容电压平衡控制是链式STATCOM的一个关键技术问题，针对此问题，采用了一种分级协调控制策略，通过改变H桥单元的输出电压和电流的夹角从而调整吸收／释放的有功功率，最终控制直流侧电容电压平衡。最后，搭建了仿真模型，仿真结果验证了控制策略的正确性和可...

| Abstract: | The topology of the cascaded STATCOM is presented, and the mathematical model is built based on the topology. Unbalance of dc-capacitor-voltage is a key technical problem of cascaded STATCOM. To solve this problem, a multi-level cooperation control strategy is used. Dc-capacitor-voltage could remain constantly, when changing the angle between H-bridge voltage and current to adjust the active power absorbed or discharged by it. The simulation results have proved the correctness and the feasibility of the control strategy. |
