The invention discloses a method for controlling a self-coupling compensation-type alternating-current voltage stabilizer. The method includes the steps that an alternating-current power voltage is divided into a plurality of voltage level intervals, and one or more voltages of output voltages of a self-coupling transformer are selected through a thyristor switch group and stacked to serve as a magnet exciting coil voltage of a compensation transformer for voltage compensation; whether a triggering control signal for controlling the thyristor switch group is correct or not is judged; when thetriggering control signal is correct, a working power source of a triggering unit is switched on; when the triggering control signal is wrong, the working power source of the triggering unit is cut off, and the input-side power supply voltage of the self-coupling transformer is controlled to be switched off to protect the thyristor switch group. According to the voltage-stabilizing controlling method, whether logical erro
