| Abstract | ||||
| This paper investigates the use of supercapacitor to mitigate the transient recovery voltage (TRV) in a simple power system. The TRV concept and the phenomena surround its occurrence such as re-ignition and restrike are represented. Also, the different waveshapes of TRV are evaluated. The effect of energizing different power system parameters, such as resistance and capacitance, resulting in TRV is evaluated. At first, the effect of energizing three different values of a damping resistance, one by one, is studied. Then, the influences of energizing of a capacitor, with three different values, on the tested system are illustrated. Finally, the effect of combining different values of the damping resistance and the capacitance are evaluated. The effect of using supercapacitor as TRV mitigation method is studied. Alternating transient program (ATP/EMTP) is used to simulate the test system and the proposed supercapacitor-based method. The simulation results ensure the validity of the proposed method. | ||||
