The stress was the study of the new methods of calculation the harmonic voltage and the harmonic current, and a new concept of filter ratio to evaluate the actual effect of single harmonic filter was raised considering the background harmonics. As well, the calculation mode of the single harmonic filter was also given based on the concept of filter ratio; it can offer effect data to evaluate the actual filter ratio of the single harmonic filter. At the same time, a method of designing the single harmonic filter was given, too, considering the background harmonics of the power system. In this paper, both the computer analysis and the proven had been done. And the result was shown to be that the voltage aberration and the harmonic current were decreased, and that the actual filter ratio of single harmonic filter was raised. The reason that we must consider the background harmonics when designing a single harmonic filter was also expatiated in this paper.

重点研究了考虑电网背景谐波下谐波电压、电流的计算方法，提出了用滤波率来评价单调谐滤波器安装容量利用率的概念，基于滤波率，分别给出了不考虑、考虑电网背景谐波时，单调谐滤波器的计算模型，为定量分析和评价单调谐滤波器的实际补偿效果提供了依据：并以此提出了考虑电网背景谐波的单调谐滤波器计算机辅助优化设计方法，并经计算机仿真分析、论证，减少了负载母线谐波电压畸变率和注入系统的谐波电流，有效地提高了单调谐滤波器的滤波效果，阐述了单调谐滤波器的设计过程中要考虑电网背景谐波的理论和实际意义。
