AIMS

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 numerical algorithms such Gauss-Siedel, Newton-Raphson will be discussed. Fault calculation and analysis, symmetrical components and protection systems: Analytical methods for solving symmetrical (balanced) faults, protection systems will be covered in details. Finally power system transient and voltage stability as well primary control systems will be analysed.

INDICATIVE CONTENT
