چکیده :

Resonance and ferroresonance in power systems are categorized as two destructive phenomena especially in HV networks which initiate in consequence of a power system event. In each event, the analysis of network voltages is conducted based on identified allowable limits by IEEE 519 standard as evaluation critera. In this paper, a novel comprehensive study approach is used for resonance and ferroresonance phenomena study in a real power system. The utilized approach comprises different steps including substation equipment modeling, EMT simulation of the probable switching events, evaluation of correspondence results, and finally detecting the probable ferroresonance occurrence. In this paper, the detailed evaluation results of a 230 kV substation are presented as an example. Using the proposed evaluations identifies the probable condition which may lead to the resonance and ferroresonance occurrence. The results are highly valuable for network operators in the prevention of unintended overvoltages occurrence.
