摘要
滤波器是动态电压调节器(DVR)工程设计中的重要组成部分,不合理的滤波器结构、参数设计会影响DVR对输出谐波的抑制效果,且会增大逆变器额定容量,文中建立了包含电容支路串联阻尼电阻影响的DVR线路侧滤波器的数学模型,分析了谐波抑制机理,推导了求解滤波器参数的解析表达式。仿真计算结果验证了该设计方法的有效性。
Filter is an important constituent in the design of dynamic voltage restorer (DVR), irrational structure and parameter of filter affect the elimination effect of DVR on output harmonics, and cause the enlargement of the rated capacity of inverter. The authors presented the filter's mathematical model of DVR at line side with damping resistance in series with capacitor branch considered, analyzed the mechanism of harmonic elimination, derived the analytical expression to solve the filter parameters. The simulation results verify the effectiveness of the presented design method.
