低压变配电系统谐波监测与治理技术

Low-voltage power distribution system harmonic monitoring and control technology

随着社会的发展,各种新型的用电设备得到广泛的使用,由于设备运行所要求的高安全性和精确性,对电能的使用和需求产生了更高的要求,但非线性负荷大量使用却带来了严重的电力污染.通过对某公司变配电室的低压变配电系统进行谐波实际监测,对监测结果做出了较为详细的描述,详细分析了谐波对电气设备危害.然后探讨了谐波治理的一般方法,针对该低压配电系统提出了一种有效的谐波治理措施并检测出了试运行后的结果,最后通过对比谐波治理前后数据,分析该技术方案优势.

With the development ofsociety, a variety ofnew electrical equipment is widely used, due to the high security and accuracy of the equipment required to run, a higher demand has generated about using and demanding for electricity, but the extensive use of non-linear loads has brought serious power pollution. Through harmonic actually monitor a power distribution system of a company＇s low-voltage power distribution room, made a more detailed description of monitoring results and gived a detailed analysis of harmonics on electrical equipment hazards. Then discussed the general method of harmonic control, proposed an effective harmonic control measures against the low-voltage distribution system and detec- ted the results of the test after then, compared the harmonic data before and after and analyzed the advantages of the tech- nology program.
