The present invention relates to a distribution net pressure reactive auto-optimization closed loop control system. The system consists of an automatic pressure adjusting program module, a remote control program module and a warning program module, which work in coordination under the assurance of system technical parameters and the pressure setup regulations in different time sections. Wherein, the automatic pressure adjusting program module operates on a PAS node and acquires real-time operation state information of a grid from SCADA so as to monitor the grid pressure and analyze the acquisition information of equipment state according to the partial voltage regulation principle; if the pressure is abnormal, the corresponding regulation measures are issued; while warning information is sent to the warning program module, a remote control executive instruction is sent to the remote control program module so as to control the lifting of an executive transformer and the switching of a capacitor and ensure the
