Zusammenfassung:	The invention discloses an analysis/evaluation system and an analysis/evaluation method for power grid fault characteristic data. Based on an equipment fault alarm message which is transmitted from an intelligent power grid scheduling control system, the equipment fault alarm message is firstly acquired, and then various kinds of alarm data in the scheduling control system are automatically gathered and combined according to fault time and fault equipment, wherein the alarm data comprise switch displacement, abrupt change in factory station accident total test and remote test, disturbance analysis short report based on PMU, fault recorded data, fault short reports based on the fault recorded data, etc. Then the alarm data are analyzed and evaluated at aspects of real-time performance, accuracy and integrity of the alarm data. Finally the data quality problems of the alarm data and the detailed original alarm data are output, thereby displaying an analysis/evaluation result for the quality of the power grid fa
