介绍了传统大功率UPS应用过程中存在的问题,对现有的两种主流替代技术(模块化UPS和高压直流)进行了介绍及对比分析,并对两种替代方案的适用场合提出了建议。目前,通信行业交流设备多采用UPS供电,但随着互联网技术的飞速发展,交流设备使用越来越多,设备功耗越来越大,供电可靠性要求也越来越高,而传统大功率UPS(本文指容量在30kV·A及以上的UPS产品)可靠性低,电流谐波大,建设成本高,供电效率低等局限性也逐渐显现,业界在努力提升传统UPS供电质量,降低供电损耗的同时,也在不断探索能够替代传统
The problems existing in the application of traditional high power UPS are introduced. Two existing mainstream alternative technologies (modular UPS and HVDC) are introduced and compared, and suggestions are made for the application of the two alternative solutions. At present, communication equipment is mostly powered by UPS. However, with the rapid development of Internet technology, more and more AC devices are used, equipment power consumption is getting larger and larger, and power supply reliability requirements are getting higher and higher. However, traditional high-power UPS (this article refers to the UPS capacity of 30kV · A and above) low reliability, large current harmonics, high construction costs, low power efficiency and other limitations are gradually emerging, the industry is trying to improve the quality of traditional UPS power supply and reduce power supply loss At the same time, it is also constantly exploring to replace the traditional
