Abstract
无变压器并联混合型有源电力滤波器(TlS-HAPf)是一种新颖的具有较强实用性的拓扑,特别适用于高压大功率系统。文中在分析该拓扑结构主电路构成和工作原理的基础上,提出将无源性理论应用到该拓扑的控制中以获取更好的静态和动态性能。首先在固定AbC坐标系下建立了TlS-HAPf模型,为简化模型将其变换到同步旋转dQ坐标系下;继而通过注入阻尼获得原系统的伴随系统及跟踪偏差的动态方程;然后通过选取存储函数并对其求导证明系统的严格无源性;最后通过伴随系统得到系统的无源控制器,给出了控制框图并将其应用到系统控制中。仿真和实验结果验证了所提出的无源性控制的正确性。
 
Transformerless shunt hybrid active power filter(TLS-HAPF) is a novel topology for active power filters with great practicality,especially suitable for high-voltage high-power system.Based on the analysis of the topological structure and working principle of TLS-HAPF,a novel passive control topology is proposed to enhance its static and dynamic compensation effect.First,the shunt hybrid power filter is modeled in the stationary abc frame and then the model is transformed to the rotating dq frame with the aim of reducing the control complexity.Then by means of injecting adjustable damping into the system to establish its associated system and get the tracking error dynamic equation.The storage function of the closed-loop system is established and derived to prove its strict passivity.Finally,the dynamic controller is derived from the associated system and the control graph is given.The simulation performed in MATLAB and experimental results verify the new approach.
