Coordination of MMC converter protection and DC line protection in DC grids

2016 IEEE Power and Energy Society General Meeting (PESGM), 2016
This paper studies the coordination of MMC converter protection and DC line protection in DC transmission networks. To quickly isolate a DC line fault, hybrid DC circuit breaker is connected at each end of every DC transmission line. DC line protection based on measuring derivative of DC voltage is employed to timely trip faulted DC line only. The goal

DC bus strength in DC grid protection

2017 International Symposium on Power Electronics (Ee), 2017
Fast detection and isolation of DC faults is recognized as the main challenge in developing DC transmission grids. Voltage source converter blocking must be prevented which can be very difficult given the large rate-of-rise of fault currents. The concept of multi-converter DC bus is introduced as a grid design approach aimed towards increasing ...

The Status of DC Micro-Grid Protection

2008 IEEE Industry Applications Society Annual Meeting, 2008
AC microgrids are a convenient approach to integrating distributed energy systems with utility power systems. On the other hand, DC micro-grids can lead to more efficient integration of distributed generation. They are the preferred topology for present shipboard, aircraft and automotive power systems and hold promise for future environmentally ...
