This course provides a detailed study of the steady-state operation and mathematical modeling of electrical transmission lines used in high-voltage power systems. The course introduces transmission line representation through two-port network theory and develops the ABCD parameter models used to analyze short, medium-length, long, and lossless transmission lines.
Participants learn how to calculate sending-end voltage, current, power, efficiency, and voltage regulation from known receiving-end load conditions. The course explains the effect of transmission line impedance, load power factor, and line length on system voltage profile and operational performance.
Advanced topics include distributed parameter modeling, propagation constant, characteristic impedance, hyperbolic functions, wavelength, and propagation velocity. The course also examines surge impedance loading, steady-state stability limits, and the relationship between displacement angle and maximum real power transfer for both lossless and lossy lines.
Each topic is immediately followed by well-chosen numerical examples and detailed steps leading to solution of each to further enhance the learning experience of the audience. Numerous worked examples demonstrate practical engineering calculations involving balanced three-phase systems, voltage regulation correction, line efficiency, and maximum loadability. Since calculation of the ABCD parameters of the long lines is dependent on sine- and cosine-hyperbolic of angles, a review of these two functions are also included.
The course emphasizes real-world transmission system behavior and provides engineers with analytical techniques used in transmission planning, system operation, and power transfer studies.
The course is intended for electrical engineers, as well as design personnel who are interested in learning fundamentals of transmission line operations.
Learning Objectives
Upon completion of this course, participants will be able to:
- Model short, medium-length, long, and lossless aerial transmission lines mathematically.
- Develop the ABCD parameters for each line type using two-port electrical network theory.
- Calculate the generating-end voltage, current, power, and power factor from the load parameters for each line type.
- Determine line losses and transmission efficiency from generation to load.
- Calculate voltage drop and voltage regulation between full-load and light- or no-load operating conditions.
- Determine surge impedance and surge impedance loading for lossless lines and calculate voltage regulation and voltage profiles for different load profiles.
- Analyze design factors, including displacement angle, line length, rated voltage, line impedance, and admittance, and explain their effects on the loading capacity of lossless and lossy lines.
- Calculate line power-transfer efficiency for lossy lines and the maximum power-transfer capacity of lossless and lossy lines.
- Determine the wavelength and speed of propagation of power on lossless lines.
