摘　　要：唯一稳态消谐法是近年出现的消除非线性系统谐振新的分析方法。该方法的基本思想是如果非线性系统存在一个非谐振的正常解,并且该系统具有唯一的稳态,则此时对应的条件就是系统不发生谐振的条件。将这一方法应用在中性点接地电力系统铁磁谐振的分析中,以向量比较原理为工具,得到相应的消谐条件。结果表明,消除谐振的条件可以用一个常数矩阵的HURWITZ条件来决定,并用数值模拟进行验证,表明结果是正确的,同时也说明唯一稳态消谐法的有效性。The exclusive stable harmonic resonance method is a new method for the analysis of eliminating non-linear system resonance.The basic idea of the method is that if the non-linear system has a non-resonance solution,and the system possesses the exclusive stability,the corresponding condition is that for the non-occurrence of resonance.The article applies the method in the analysis of magnet resonance of neutral point grounding electric power system,and generates the corresponding resonance conditions with vector comparison principle as the tool.Results show that the condition for eliminating resonance can be decided by HURWITZ of a normal matrix,and be validated through numerical simulation.This also proves the validity of the exclusive stable harmonic resonance method.
