关于APF的一个专业术语的翻译

For active power filter application, the bandwidth of themultilevel converter has to be decided by the highest harmonic
to be compensated. Generally, 5th, 7th, 11th and 13th are the dominant harmonics at the medium voltage power line. Considering the 500–700 Hz switching frequency of the medium voltage power device, a five level cascaded H-bridge inverter based active filter is proposed here. The system configure is shown in Fig. 1. The design is based on the medium voltage applications (2.3–13.8 kV). The converter is composed of six H-bridges and six dc capacitors. It is connected to the power line through a 5–10% per unit inductor only。
当中最后一句It is connected to the power line through a 5–10% per unit inductor only。中描述电感的“5-10% per unit”是什么意思，标幺值的意思吗？敬请专家指点。

这个是标幺值！ 基准值为母线电压和APF容量。
