近年来,随着电力电子技术的不断发展,各类电力电子设备在能源系统、工业领域、民用建筑、电气化交通中应用日益广泛,电网谐波问题越来越为人们所重视。各国对电网质量的评价不再仅限于频率和电压的稳定程度,对谐波也相应制定了国际和国家标准加以限制。据有关资料统计,在各行业产生的谐波量中,来自民用建筑的约占40%。本文着重对民用建筑内配电系统谐波污染问题进行探讨和介绍。
In recent years, with the continuous development of power electronic technology, various types of power electronic equipment have been widely used in energy system, industrial field, civil construction and electrified transportation. Harmonic problems of power grid are paid more and more attention. The evaluation of grid quality in various countries is no longer limited to the stability of frequency and voltage, but also limits the harmonics to corresponding international and national standards. According to the statistics, about 40% of the harmonic waves generated by various industries come from civil buildings. This article focuses on the civil building distribution system harmonic pollution problems discussed and introduced.
