现代化智能建筑中用电负荷的电能质量治理设备选择

Selection of Power Quality Control Equipment for Electricity Load in Intelligent Building

智能建筑根据功能的需求会使用不同类型的负荷,其中包含了许多典型的电力电子非线性设备,这些设备运行时给配电系统带来电能质量问题。结合某影剧院电能质量治理方式,对比了传统补偿滤波方案、有源滤波补偿方案、SVG混合动态补偿方案,归纳了针对不断更新的非线性负荷所在的配电环境采用新型治理装置的优势。提出在建筑电气设计时需了解智能建筑项目负载类型,以合理选择电能质量治理设备的类型和容量。

Modern intelligent building uses different types of loads according to the requirements of function,which contains many typical nonlinear power electronic devices,and these devices operations bring the power quality problems for distribution systems. Combining by a cinema as an example,this paper compared traditional compensation filtering scheme,new active power filtering scheme,and SVG mixed dynamic compensation scheme. Aiming at the updating power distribution environment of the nonlinear loads,the advantages of new control device were summarized. It is pointed out that the load types of intelligent building should be understood when the building project is designed,in order to reasonably choose the power quality control device type and capacity.
