Simulation Analysis on Ferroresonance of Power System Based on Matlab

In the neutral point non-earthed complicated power system,ferroresonance over vohage caused by single- phase earthed fault happens frequently.Simulation based on MATLAB is employed in this paper to achieve digital calcu- lation and simulation of the ferroresonance transient process due to matching non-linear exciting inductance of PT with network to earth capacitance.It provides a research platform to restrain the occurrence of the ferroresonance.
