本文将先进的H ∞最优控制理论应用于一种基于有源滤波技术的新型主辅消弧线圈。给出了H ∞标准控制框图和模型匹配系统的状态空间表达式。辅助消弧线圈由单相并联电压源逆变器（VSI）构成，它产生的谐波小，能自动补偿接地电容电流，响应速度快，范围宽。通过注入有功电流，实现了接地故障电流的全分量化。文中详细分析了该装置的工作原理，提出了一种预置式与随动式相结合的补偿方式。设计了连续时间H ∞控制器，实现了所需的所有性能和鲁棒性。计算机仿真和10 kV物理仿真实验结果证明了该方法的有效性。
In the paper, the advanced H-Infinity optimization control theory is applied to a new type principal- auxiliary arc-suppression coil (ASC) based on active filter technology. The H-Infinity standard control block diagram and the state space expression of model matching system are given. The auxiliary ASC composes of a single-phase shunt voltage source inverter (VSI), which produces little harmonics and automatically compensates the grounding capacity current with rapid response in a wide range. By injecting the active current, it realizes the full component of the earth-fault current. In this paper, the work principle of the new device, and a combinational compensation mode of presetting mode and following-setting mode are analyzed in detail. A continuous time H-Infinity controller is also designed which achieves all performances and robustness properties required. The results of the computer simulation and 10 kV physical simulation experiments prove the validity of our approach.
