办公建筑低压配电系统谐波治理设计

Design for Harmonic Control in Low-voltage Distribution System in Office Buildings

办公建筑具有大量小功率的单相非线性负荷,谐波污染严重,并以3次谐波为主。其低压配电系统应根据谐波源特点采取治理和防范措施。通过分析某办公建筑配电系统谐波实测结果,介绍了某新建办公建筑的谐波治理设计。

There are a large number of low-power single-phase non-linear loads with serious harmonic pollution, mainly third harmonic in office buildings. Control and preventive measures should be taken in its low-voltage distribution system on the basis of the characteristics of the harmonic sources. In this paper, through the analysis of the measurement results of the harmonics in distribution system of an office building, a harmonic control design for a new office building is introduced.
