医院供配电系统谐波测量和分析

摘要

To suppress more and more serious harmonic pollution of hospital power supply and distribution system, a deep un-derstanding of hospital harmonic distribution is needed. This paper emphatically analyzed the harmonic pollution and harmonic source distribution of a hospital power supply system, based on the harmonic test data obtained by FLUKE 43B, and then sum-marised the measures to suppress the harmonic pollution according to its feature. Test results show that there is terrible harmonic pollution of hospital power supply and distribution system. The equipments that are tested are advanced and complete, so the har-monic data is representative and could provide reference to the harmonic studies, harmonic suppression and filtering equipment se-lection of hospital power supply and distribution system.%为治理日趋严重的医院供配电系统谐波污染，需要深入了解医院谐波分布。利用FLUKE 43B对某医院进行现场谐波测试，基于所得数据重点分析了医院供配电系统谐波污染和谐波源分布情况，根据医院谐波污染特点总结了治理方法。结果表明：医院供配电系统存在严重的谐波污染。被测量医院设备先进，种类齐全，测试所得数据具有较强的代表性，可为医院供配电系统谐波研究、谐波治理和滤波设备选择提供基础数据参考。
