摘要

在UPS旁路运行过程中，不间断电源(UPS)与发电机并联会在一定条件下产生较大的循环地电流。本文探讨了导致这种系统行为的现象，给出了实际记录的数据，并讨论了减少或消除这种循环电流的方法。

Investigation of circulating ground currents occurring during UPS/generator paralleling

The paralleling of uninterruptible power supplies (UPS's) with generators during UPS bypass operations can result in high-magnitude circulating ground currents under certain conditions. This paper explores the phenomena that cause this system behavior, presents data from an actual documented occurrence, and discusses methods to reduce or eliminate such circulating currents.
