sci.power-flow-Newton-Raphson-bus Calculator
Calculates bus voltage magnitudes and angles, and line power flows in an AC power system using Newton-Raphson load flow analysis. Load flow converges in 3–5 Newton-Raphson iterations — it forms the core of power system planning, security assessment, and optimal power flow (OPF).
Inputs
V1 Pu
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
V2 Pu
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
Delta Deg
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
X12 Pu
Reference formula or conversion factor shown for context.
Results
active power flow P₁₂ (pu)
Reference formula or conversion factor shown for context.
reactive power flow Q₁₂ (pu)
Reference formula or conversion factor shown for context.
apparent power S₁₂ (pu)
Sample size or count used in the calculation.
power factor
A dimensionless multiplier applied in the calculation.
