The setting parameters and the preset parameters are compared, whether the distribution automation terminal is in a normal operation state or not can be determined, and if the setting parameters and the preset parameters are different, the distribution automation terminal is not in the normal operation state and needs to be self-healed.
If the setting parameter meets the preset self-healing rule, step S250 is executed.
And S250, calling back the setting parameters of the power distribution automation terminal to preset parameters.
Wherein, because the initial parameter of distribution automation terminal is the setting parameter when normal operating usually, through setting up initial parameter to the parameter of predetermineeing when setting parameter satisfies the rule of predetermineeing the self-healing, automatically will distribution automation terminal's setting parameter callback to the parameter of predetermineeing can realize distribution automation terminal's automatic recovery, has realized the self-healing process promptly.
