发电机组和UPS组成的供电系统为敏感性负载提供连续、可靠及安全的电源,设备的选型需要考虑发电机组和UPS的匹配问题1.UPS和发电机组的额定功率配备有PFC整流器或THM有源12脉冲整流器的UPS,其输入功率因数很高(大于0.9),因此能最有效地使用发电机组。更重要的是,要控制UPS上线的谐波避免对输出阻抗较高的发电机组产生任何问题。
The power supply system consisting of genset and UPS provides continuous, reliable and safe power supply for sensitive loads. The selection of equipment needs to consider the matching problem between genset and UPS 1. The rated power of UPS and genset is equipped with PFC rectifier or THM The source 12-pulse rectifier UPS, which has a high input power factor (> 0.9), enables the most efficient use of the generator set. More importantly, controlling the on-line harmonics of the UPS avoids any problems with the generator with higher output impedance.
