The invention provides a smart distribution grid semi-closed loop self-healing control method aiming at the actual situation that an original self-healing scheme can not continue to be carried out probably because of remote control failure in the actual operation according to an operation sequence obtained through the self-healing scheme when a smart distribution grid carries out self-healing control. According to the technical scheme, when the smart distribution grid breaks down, the remote control operation sequence of the self-healing recovery scheme is obtained, and each step of remote control operation is carried out after being determined errorless by a dispatcher; once remote control failure happens, a standby self-healing scheme and a standby operation sequence are generated, and distribution grid self-healing is achieved according to the standby operation sequence; finally, it is ensured that the distribution grid operates in the optimum mode after seal-healing through distribution grid reconfiguration. According to the smart distribution grid semi-closed loop self-healing control method, the semi-automatic self-healing automatic control mode is achieved, the automation level of a self-healing control system is improved, self-healing scheme correction is carried out aiming at the remote control failure probably happening in seal-healing control, and the effectiveness and feasibility of distribution grid self-healing control are guaranteed.
