Simulation and Analysis of the Neutral Resistance Grounding of 1140V Power System in Coal Mine

Abstract:

The neutral grounding mode through resistance and the grounding resistance value of 1140V coal mining distribution system are studied and simulated in this paper. According to the 1140V power supply system parameter of the underground mining area of a coal mine, the PACAD software is used to establish the simulation model of power system. The single-phase ground fault caused by the insulation deterioration of the load equipment is simulated through setting single-phase ground fault in charge line of load side. The advantage of neutral grounding mode through resistance is analyzed through the simulation result. According to the distributed capacitance over the ground of simulation data and power network, the value range of the neutral point grounding resistance can be obtained.
