The invention relates to the arc quenching and voltage stabilization technology of a power distribution network neutral point grounding fault point and particularly relates to an intelligent power distribution network neutral point grounding active full-compensation control system. The intelligent power distribution network neutral point grounding active full-compensation control system is characterized in structure by comprising a data acquisition system, a control circuit, a driving circuit, an inversion circuit, a filter circuit, an access circuit and a control power source, wherein a data acquisition end of the data acquisition system is connected with an electric power system, an output end of the data acquisition system is connected with the control circuit, a control output end of the control circuit is respectively connected with the driving circuit and the control power source, and the inversion circuit is connected with an input end of the electric power system respectively through the filter circuit and the access circuit. The system is advantaged in that a voltage recovery open loop and closed loop control method taking a dissonance degree, a damping rate, reactive compensation current and active compensation current as parameters is provided according to analysis, timely self-healing of a fault is guaranteed, moreover, the system voltage can recover to a normal state rapidly.
