Abstract：Harmonic is an important factor affecting the power quality of the terminal grid,which can be caused by many reasons and fluctuates greatly,

making the solution of reasonable harmonic control in the design stage an annoying problem for the electrical designers. The harmonic control practices in a actual case of power supply and distribution system in a laboratory building are introduced in detail in the hope of analysis conclusion offering references for electrical designers in their design.

Key words：harmonic;harmonic current;total harmonic distortion of voltage; active filter;harmonic source;harmonic ratio;common connection point;harmonic measurement point

摘　要：谐波是影响终端电网电能质量的重要因素，谐波产生的因素很多，波动变化也比较大，如何在设计阶段采用合理的谐波治理方案一直是困扰电气设计人员的难题。结合某实验大楼供配电系统谐波治理实际案例详细介绍谐波治理过程，分析结论希望对电气设计人员的具体设计工作有所帮助。
