Analysis of single phase ground fault characteristics of low resistance ground active distribution network

Journal of Physics: Conference Series, 2021
Abstract A large number of distributed generators access to low resistance grounding system may have great influence on the fault characteristics of single phase ground. In view of low resistance ground active distribution network, the connection mode of Inverter-interfaced Distributed Generators (IIDG) is discussed comprehensively based

Research of Single-phase Grounding Fault Simulation for Small Current Grounding System

DEStech Transactions on Environment, Energy and Earth Sciences, 2017
Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system
