Analysis of multi-grounded four-wire distribution systemsconsidering the neutral grounding

摘要

This paper has explored the inherent characteristics ofnmulti-grounded three-phase four-wire distribution systems undernunbalanced situations. The exploration also involved the effects ofnneutrals and system grounding. Power engineers have often disregardednthese effects while analyzing a power system. The simulation tool isnPSpice for Windows. It is capable of representing and simulating thenequivalent model with an explicit neutral wire and groundings of anmulti-grounded distribution system. In this paper the equivalent modelnof a full-scale multi-grounded distribution system implemented by PSpicenis introduced. Simulation results have illustrated the effects ofnneutrals and system grounding on the operation characteristics ofnmulti-grounded four-wire distribution systems
