摘  要:
Unique steady state elimination method is a new method for eliminating resonance in nonlinear system presented recently.Its basic idea is that if there is a normal(non-resonance)solution for the system,and the steady state of system is unique,then the corresponding conditions are the conditions for eliminating resonance.In this paper,this new method is applied to analyze the eliminating of ferroresonance in neutral grounding power system by zero-sequence resistor.Based upon strongly structured perturbation theory,the conditions for eliminating this ferroresonance are obtained,which can be determined by the Hurwitz conditions of some constant matrixes.The conclusions to be proved by numerical simulation are correct,and it shows the effectiveness of unique steady state elimination method.
