【Abstract】 According to the characteristic modes of jump resonance,a mathmatic model of fundamental-frequency ferroresonance in 6~35 kV distribution system is derived,based on the describing function concepts of nontineacontrol theory. A numerical method is proposed to predicting the possibility of jump resonance being sustained by the system. the results predicted by this method are compared with the ones obtained from simulation experiments. it shows the effectiveness and applicability of our method.更多还原
