Article Preview

Neutral point grounding which is related to voltage level, network structure, insulation, communication and relay protection is very important problem to power system. Nowadays, the choice of neutral point grounding mode mainly relies on operation experiences or theoretical analysis which could not give a direct view of the dynamics of electric power system during disturbances. Therefore, this paper has established the simulation model of electric power system neutral point grounding with PSCAD/EMTDC to show the dynamics of neutral point grounding when disturbed by single-phase grounding in transmission lines, and the application of each neutral point grounding mode has been analyzed according to simulation results. The dynamic model of neutral point grounding in this paper is meaningful to the analysis of high-order, non-linear transients of power system as well.
