← TechnologyWhich consequence results when undampened oscillations propagate on a power transmisson grid?
A)Cascading grid failures occur✓
B)Transformer core saturation decreases
C)Line inductance is significantly stabilized
D)System frequency regulation improves
💡 Explanation
Cascading grid failure occurs from undampened oscillations because the resonance progressively destabilizes connected generators via sympathetic oscillations, rather than localizing the fault. Therefore, complete system failure happens rather than improvements to system frequency or stability.
