The invention provides a power fault repairing system and a power fault repairing method adopting the same. The power fault repairing system comprises a control master station, one or more control substations connected with the control master station as well as one or more execution stations connected with each control substation, wherein the execution stations are connected with components of a power system; the control master station is used for monitoring whether the power system has a fault, determining a fault repairing strategy, acquiring the number of controllable components and weight coefficients of the control substations from the one or more control substations and decomposing the fault repairing strategy; each control substation is used for decomposing a fault repairing sub-strategy according to the number of the controllable components; each execution station is used for determining a strategy execution object according to preset strategy execution rules and executing a fault repairing strategy unit on the strategy execution object. The power fault repairing system increases the power fault repairing efficiency.
