In order to reduce the output voltage stability of power grid, reducing safety accidents because the voltage of the mutation, the automatic control method of feedback suppression based on adaptive coupling overpressure accidents in high incidence area of grid voltage. The relationship between the output voltage and the power grid construction model of electromagnetic field of magnetie dipole, load, power factor and current between the construction of the optimization objective function of voltage control combined with electromagnetic coupling model, the adaptive coupling of differential voltage suppression and low voltage feedback modulation method, realizing the automatic voltage control. The simulation results show that the control method is used to control the power grid voltage, the output voltage is stable and the error is low.
