The invention discloses a power grid fault recognition method on the basis of power grid fault intelligent recognition equipment. The power grid fault recognition method includes particular steps of acquiring current and voltage information of live lines and zero lines of power grids by a power grid data acquisition module A and a power grid data acquisition module B, processing comparison resultsby a power grid management processor and judging whether the power grids have faults or not; periodically operating an equipment information acquisition module under the control of the power grid management processor, acquiring information such as equipment configuration parameters, operation information, action information, wave recording files and fault distance measurement of equipment in thepower grids after the equipment information acquisition module is started, matching the equipment information acquisition module with the power grid management processor and carrying out automatic analysis to generate complete power grid phase reports. The power grid fault recognition method has the advantages that the faults of the power grids can be effectively recognized by the aid of the powergrid fault recognition method, an alarm can be timely raised, switch on and off of monitored electric power equipment can be controlled, and accordingly accidents can be effectively prevented; faults, alarm, actions and the like of protection equipment further can be monitored, operation states of the equipment can be protected, and the equipment of the power grids can be periodically monitored.
