【摘要】 智能建筑三A系统(设备自动化系统、办公自动化系统、通信自动化系统)中大量自动化设备需要高质量的电源,但同时其中相当数量的设备由于具有非线性负载特性,又是引发谐波畸变的扰动源。因此对智能建筑中的自动化设备所产生谐波的检测是一项重要工作,它对谐波畸变的危害性分析和防范有着重要意义。更多还原

【Abstract】 In intelligent buildings’ three A system (equipment automation system,office automation system,communication automation system).Lots of automatic equipments need power sources of high quality.But at the same time a quite amount of them with a non-linear loads characteristics,which is the cause of harmonic distortion.So detecting the harmonic distortion which generated by the equipments in intelligent building is an important task.It is great significance to analysis the harmfulness of harmonic distortion and prevent them.更多还原
