Grounding fault detection and type determination of substation DC system
نویسندگان
چکیده
The DC system is used as the power supply for all kinds of protection, measurement and control, safety automation other devices in substation. It fundamental guarantee control protection. If substation fails, it will have a destructive impact on entire function. Based this, order to solve problems maloperation refusal protection device caused by grounding fault system, method combining unbalanced bridge with leakage current sensor proposed detect resistance bus branch. On this basis, neural network optimized quantum particle swarm optimization determine type. Finally, effectiveness verified MATLAB/Simulink simulation.

Optimal Analysis of Grounding System Design for Distribution Substation
Abstract—This paper presents the electrical effect of two neighboring distribution substation during the construction phase. The size of auxiliary grounding grid have an effect on entire grounding system. The bigger the size of auxiliary grounding grid, the lower the GPR and maximum touch voltage, with the exception that when the two grids are unconnected, i.e. the bigger the size of auxiliary ...
متن کاملHV Substation Overvoltage Computation Taking into Account Frequency Dependent Transients on the Substation Grounding System
This paper describes methodology for the computation of the electromagnetic transients in the high voltage substations, taking into account transients on the substation grounding system. Simulation technology is based on the system decomposition. Interconnections between different subsystems are done in each time step using Thevenin equivalents. Frequency dependent impedance of grounding conduc...
