摘要
剧院建筑中大量使用晶闸管调光设备等非线性设备产生谐波,对电网、用电设备、线路电缆等造成一定的影响。结合某剧院建筑供电系统中有源滤波器的应用情况,介绍了谐波的产生及对舞台、灯光音响的危害,阐述了有源滤波器进行谐波治理后的效果评估情况,说明有源滤波器在艺术中心,剧院等场所的使用意义。
As the extensive use of SCR dimming equipment and other nonlinear devices,in theater project,a lot of harmonics are generated which have affected on the power grid,electrical equipments,and cable lines. Combined with the application of active power filter（ APF） in the theater project,this paper described the generation of harmonics and its hazards to stage management,lighting and sound. By using of APF,the effect evaluations of harmonic elimination were elaborated. It shows the significant value of APF in arts center,theater and other buildings.
