Load-flow¶

• Total losses: 0.00 kW
• Worst utilisation: 125.1 % (CBL-SUB-RMU2-001)

Short-circuit¶

Short-circuit has not been run for this project.

Methodology¶

• Ampacity (Iz): IEC 60287-1-1 (native engine) or CIGRE TB 963 V5 FEM where method selected.
• Load-flow: backward/forward-sweep (Gauss-Seidel).
• Short-circuit: IEC 60909 symmetric three-phase fault at each bus, Thevenin impedance reduction.
• Generated by EmptyOS cable-network app for project demo-windfarm-50mw.
