摘要： A method and an apparatus for identifying faults in a computer-aided manner for a technical system including a switch and a switch drive is provided. A fault or a disruption in the switch and/or in the switch drive is detected by capturing a temporal profile of a measurement variable of the switch drive. A simulation model is provided for the technical system and a fault situation is set by means of setting values of the simulation model, wherein the setting values are assigned to the fault situation. The technical system is simulated by means of the simulation model, wherein a simulated temporal profile of the measurement variable is captured. The simulated temporal profile is compared with the temporal profile of the measurement variable of the switch drive, wherein the fault situation is assigned to the detected fault on the basis of the comparison.
