The Application of the Frozen Coefficient Unique Steady State Elimination Method to the Eliminating of Ferroresonance

将唯一稳态消谐法应用在消除中性点接地电力系统铁磁谐振的分析中,并以冻结系数法为工具,得到了相应的结果。分析表明,消除谐振的条件可用一简单矩阵的稳定条件来决定,且通过数值模拟进行验证,表明了结果的正确,也说明了唯一稳态消谐法的有效性。

Unique steady state elimination method is a new method for eliminating resonance in nonlinear system presented recently.The aim of this paper is to analyze the eliminating of ferroresonance in neutral grounding power system with frozen coefficient by this method,and corresponding results are obtained.The conclusion shows that the conditions for eliminating this ferroresonance can be determined by the Hurwitz conditions of a simple matrix.The conclusions of this paper are proved correct by numerical simulation,and meanwhile it shows the effectiveness of unique steady state elimination method.
