Key Factors Affecting Transient Stability
Key Factors Affecting Transient Stability: 1. Generator Inertia: Higher inertia helps resist speed changes, improving stability. 2. Fault Clearing Time: Shorter times reduce disturbance impact, enhancing stability. 3. Excitation System: Fast-responding excitation stabilizes voltage after disturbances. 4. System Strength: High short-circuit capacity supports better stability. 5. Operating Conditions: Generators near max load are more prone to instability. 6. Transmission Reactance: Lower reactance lines improve power transfer and stability. 7. Disturbance Location/Type: Faults closer to generators are more destabilizing. 8. Network Topology: Well-connected systems with redundancy handle disturbances better. 9. Power System Stabilizers (PSS): These devices damp oscillations and improve stability. 10. Governor Response: Quick mechanical adjustments help maintain balance. 11. Renewable Integration: Low-inertia renewables reduce stability, mitigated by storage or synthetic inertia.
