摘要
Ferroresonance over-voltage is a destructive factor in power systems and keeps on causing accidents. So far no correct approaches have been found in the theoretical analysis of this complex physical process. In order to avoid difficulties, people usually explain the mechanism of ferroresonance over-voltage with the help of the knowledge about resonance in nonlinear oscillating systems with single degree of freedom. From this point of view, some measures of removing ferroresonance over-voltage have been proposed. However, power systems are not definitely the systems with single degree of freedom, the aforementioned explana-
