摘要

直流微电网可以为数据中心或私人住宅等商业应用的安装提供许多优势。在本文中，对这种网格向双极结构(例如±380 VDC)的未来扩展进行了评估。重点是各种故障情况，它们对电网的影响以及维护电网安全的可能解决方案。为此，建立了实验室规模的双极测试电网，并对其进行接地故障、中性点损耗和负载脱落。

Safety considerations for the operation of bipolar DC-grids

DC microgrids can offer many advantages for an installation in commercial applications like data centers or in private homes. In this paper, future expansion of such grids towards a bipolar architecture (e.g. ±380 VDC) is evaluated. The focus lies on various fault situations, their effects on the grid and possible solutions to maintain grid safety. For this purpose, a laboratory scale bipolar test grid is set up and subjected to ground faults, loss of neutral and load shedding.
