探讨了传统的谐波阻抗圆统计方法对弱交流系统换流站交流滤波器设计带来的不利影响,以糯扎渡直流工程送端普洱换流站为例,采用分类谐波阻抗统计方法进行了分析,指出直流孤岛方式应按直流输送容量分类统计谐波阻抗,直流联网方式则应按直流输送容量及交流系统强度分类统计谐波阻抗。

Investigating the adverse influence of traditional statistical harmonic impedances in a weak AC system on its AC filter design,and taking Puer converter station in Nuozhadu HVDC project as an example,this paper adopts the harmonic impedances from classification statistics to analyze the design of AC filter,pointing out that the harmonic impedances should be collected statistics by classification of DC transmission capacity for the islanded operation mode while by classification of both the DC transmission capacity and the AC system strength for the coupling operation mode.
