Power Systems Simulation Laboratory
This simulation-based laboratory complements Introduction to Power Systems with practical studies in transmission-line modeling, power flow, transformers, HVDC, power quality, synchronous generators, voltage regulation, transient stability, economic dispatch, faults, protection, and switching over-voltages.
Objectives
- Build and analyze electric-power-system models using MATLAB and Simulink, PowerWorld Simulator, and PSCAD/EMTDC.
- Calculate transmission-line parameters and evaluate power flow, bus voltages, transformer controls, and HVDC transmission.
- Investigate power quality, synchronous-generator behavior, voltage regulation, and reactive-power compensation.
- Simulate transient stability, automatic generation control, economic dispatch, and reliability planning.
- Analyze short-circuit faults, transmission-line loading, relay settings, switching over-voltages, and surge-arrester protection.
