This thesis covers the implementation of a methodology for detecting transient instability failures in the Center-South Transmission System of Peru. For this, three case studies were selected considering a replacement time greater than the average (190 ms), an interrupted power greater than 32 MW and the type of line according to its voltage (500 kV). The first case analyzed was the disconnection of line 5032 (Chilca-Poroma), which had a replacement time of 5h 49 min and an interrupted power of 195.17 MW. Applying the detection methodology, an angle of critical phasor of 0.932 rad was obtained and a time saving of 1.41s with respect to the reference phasor value proposed by the operability study (3.1416 rad), in which the beginning of a process of transient instability. The second case analyzed was the disconnection of line 5011 (Chilca Nueva-Fénix), which had a replacement time of 4h 14 min and an interrupted power of 529.6 MW; obtaining an angle of critical phasor of 1.26 rad and a time saving of 4.75 s. Finally, the third case analyzed was the disconnection of line 5034 (Poroma-Ocoña), which had a replacement time of 1h 30 min and an interrupted power of 332 MW; obtaining an angle of critical phasor of 1.22 rad and a time saving of 6.4 s. Once this analysis was carried out, it can be concluded that the application of the detection methodology was successful, since it allowed a saving of time compared to the initial instability reference value, which would help reduce the time that it would take for a transmission line to reinsert to the SEIN.
