西门子变频器的谐波计算

The Harmonic Calculation of Siemens Converters

本文介绍了变频器谐波对电网的影响,以及我国对电网谐波的标准和计算方法。从而,提出了西门子工程型变频器的一种谐波计算方法。为读者今后在选用西门子变频器时,评估变频器系统对自身电网的谐波影响提出了宝贵的建议。

This paper introduced Influence of harmonic for converter on the power grid,and harmonic standard and calculation methods in China.Therefore,the paper proposes a kind of harmonic calculation method for Siemens engineering type converter.It is a useful suggestion to evaluate influence of harmonic for converter system on their own grid for the reader who selected Siemens converters in the future.
