针对链式静止同步补偿器（STATCOM）直流侧电容电压平衡问题,建立了链式STATCOM的单相等效数学模型,在分层控制架构的基础上,提出相邻电感均衡能量来控制其各模块直流侧电容电压平衡。上层通过前馈解耦控制实现系统总的有功和无功控制;下层采用所提出的控制方法,以电感作为中间储能单元转移电压高的直流侧电容能量来控制直流侧电压大小;最后给出了相邻电感均衡能量控制具体的实现方法。仿真与试验结果表明,方法可以有效地稳定链式STATCOM直流侧电容电压,具有精度高、速度快、控制方法简单等特点。

英文摘要：

For tyhe chain STATCOM DC capacitor voltage balancing problem,this paper created a mathematical model of the single-phase equivalent chain STATCOM in hierarchical control architecture based on the proposed balanced adjacent inductance energy to control its various modules DC capacitor voltage balance. The upper realizes,by feedforward decoupling control system,the total active and reactive power control; the lower,using the proposed control method,to control the DC voltage,taking inductor as an intermediate storage unit to transfer high voltage DC capacitor energy; finally,the adjacent inductance balanced energy control specific method is given out. The simulation and experimental results show that this method can effectively stabilize the chain STATCOM DC capacitor voltage,it has high precision,speed,control simple.
