| Abstract: | In the neutral grounded power system, the mathematic model of ferroresonance overvoltage is built up, and the heteroclinic orbit is calculated. Based on Melnikov method, the chaos threshold value of the system is obtained, that is the parameter domain and the condition of exciting chaos. At last the existence of the periodic solution of the system is discussed. All of these will provide the theorem basis to control and restrain the chaos in overvoltage effectively. |
