Abstract

The article describes the Simulink- model for the study of processes of single-phase ground faults in the power supply grids. There are simulation results for ground faults in the circuit 6 kV with isolated or compensated neutral. The model allows searching the based settings for arc suppression coils and relay protection units. The results of modeling formulate requirements for devices which compensate currents of single-phase ground fault.
