Fault clears at angle ( \delta_c ). System stable if area ( A_1 ) (accelerating) = area ( A_2 ) (decelerating).
[ Z_pu,new = Z_pu,old \times \left( \fracV_base,oldV_base,new \right)^2 \times \left( \fracS_base,newS_base,old \right) ]

[ \textpu value = \frac\textActual value\textBase value ]
Critical clearing angle ( \delta_c ) increases with higher inertia, faster fault clearing. 8. Conclusion & Summary Tables (PPT Final Module) Key formulas card: Slide 1: Title – Load Flow Analysis Slide
Derived bases: [ I_base = \fracS_base\sqrt3 V_base, \quad Z_base = \frac(V_base)^2S_base ]
