摘　　要：无源滤波器因其成熟的技术和较低的成本而得到了大量应用,其中二阶高通滤波器和C型阻尼滤波器广泛用于新型电力系统谐波问题的治理。然而现有研究缺乏对每种滤波器特性的揭示,使得设计者在选择最优拓扑问题上存在困难。为此,深入研究了2种高通滤波器的拓扑特性,并着重考虑系统电压对滤波器成本的影响,归纳出2种高通滤波器的内在特性以及它们的最优应用场景,并提出可用于低压等级到高压等级的普适性结论,有利于解决滤波器拓扑选择问题并指导滤波器组设计。Passive filter is extensively used in new power systems because of its mature technology and low cost,and two types of high pass(HP)filters,i.e.the second-order HP filter and type-c damped filter,are widely used for harmonic treatment However,the existing researches cannot yet clearly reveal the characteristics of each type of filters,which makes it difficult for the designer to select the optimal filter topology under different circumstances.As a result,this paper provides a deep insight into the topological characteristics of the two types of HP filters with focus on the influence of system voltage on the filter cost,and summarizes the inherent characteristics of the two type of HP filters and their optimal application scenarios.Universal conclusions are reached in the paper,which are applicable to different voltage levels ranging from low voltage to high voltage,and helpful to solve the problem of filter topology selection and guide the design of filter packages.
