| Abstract: | In the neutral point non earthed complicated power system, ferroresonance overvoltage caused by single phase earthed fault happens frequently. This paper employs MATLAB based simulation to achieve digital calculation and simulation of the ferroresonance transient process due to matching of non liner exciting inductance of PT and network to earth capacitance. Different ways about ferroresonance suppression and their effects are discussed and simulated as well. |
