Aims and Scope

The scope of the course is the comprehension of the meaning, the role and the operation of Electrical Power Transmission Systems in the frame of the integrated Electrical Power Systems, as well as the thorough investigation of the traditional and digital techniques used for the analysis of Power Transmission Systems.

Course Description 

Theory

R, L, C line constants of electrical transmission lines. Equivalent circuits of transmission lines. Short, medium and long transmission lines. Voltage and power circular diagrams. Voltage control. Active and reactive power flow in electric energy transmission systems, target determination, variables assessment, equations formation. Application of digital techniques. Power flow control, dispatching centers, control parameters. Economical functioning of electric power systems. Power system stability. Travelling waves. The Corona phenomenon. Insulators for overhead lines. High voltage equipment. Symmetrical short circuit fault calculations. Fundamental principles of mechanical design for overhead lines.

Laboratory

The laboratory part of the course consists of practical implementation of several electrical transmission system arrangements developed through appropriate models of lines, loads and supply systems, aiming at the study of the whole power transmission system and of each separate component of it.  

Expected Course Outcome

• Recognize a transmission system as a discrete part of an integrated Electrical Power System
• Understand in great extent the theoretical background determining the structure and the operation of electrical power transmission systems.
• Be able to implement the above mentioned theoretical principles for the study and analysis of the electrical power transmission systems.
