It has been a hot issue for decades about the faulted feeder selection as well as the fault location methods for the neutral un-effectively grounded distribution network. As for the existing methods dealing with the single-phase earth fault in this kind of network, they show great limit as the impact of the Petersen-coil is usually not taken into consideration, and the zero-sequence current is in...
This paper presents the development of modular dual-half-bridge (MDHB) bidirectional dc-dc converter as the dc-dc stage of 10 kVA single phase solid state transformer (SST) for future renewable electric energy distribution and intelligent power management systems. The dc-dc converter, connected to 12 kV DC bus generated by an ac-dc rectifier interfacing with 7.2 kV electric utility grid, is to provide...
