This subject provides an insight into the basic elements of electrical power transmission and distribution systems such as generators, transmission and distribution lines, and loads. It offers analytical tools for analysis of basic operations of these systems. Problems related to power flow and use of Newton-Raphson will be discussed. Fault calculation and analysis, symmetrical components, and analytical methods for solving symmetrical (balanced) faults will be covered. Principles, concepts and problems related to economic dispatch as well as frequency regulation in power systems will also be discussed and analysed. Finally, power system transient and voltage stability will be introduced.
- Comprehensive analysis of single and three-phase AC power circuits, which includes calculations of real, reactive and complex powers, and power factor correction;
- Calculation of active and reactive power transfer between buses, maximum power transfer, static stability limit, power circle construction and analysis;
- Synchronous generator models;
- Power flow calculations, Newton-Raphson method;
- Fault calculations, balanced and unbalanced, symmetrical components;
- Economic dispatch;
- Frequency and voltage regulation;
- Voltage stability, transient stability;
- Computer simulation, PowerWorld.
