Fault Analysis
Equivalencing
Worked with steady state phasor/impedance models but ideas carry through to other network analysis
31. Component Models (Primitives) Lines
Transformers
Machinery
The primitive relates terminal voltages to terminal currents
- differential equations for transients/stability
- phasor/impedance models for sinusoidal steady state
- may be nonlinear
Models go with analysis needs
Model detail must be balanced against data(parameter)
availability/accuracy
Modern software databases allow for complete detail
