Modeling and Simulation Analysis of Grounding Fault in Power System Based on MATLAB
摘要
Abstract
The grounding mode of neutral point of power grid directly affects the insulation level, voltage level, reliability of power supply and the way of line protection.The grounding fault is closely related to the neutral grounding mode of power system.The same fault condition but in different neutral grounding mode, the fault characteristics, consequences and harms of grounding fault are different, so the protection strategies are different as well.Based on the three kinds of grounding modes which are direct grounding, non-grounding and arc-suppression-coil grounding, the fault characteristics of the three kinds of grounding being the objects of study, the MATLAB software was used to modeling simulation and then the theoretical comparison analysis was done on the results.The simulation results show that the theoretical analysis results are in accord with the simulation and the engineering practices.关键词
