Preamble: This course is an extension of power systems–I course. It deals with basic theory of transmission lines modeling and their performance analysis. Transient in power system, improvement of power factor and voltage control are discussed in detail. It is important for the student to understand the mechanical design aspects of transmission lines, cables, insulators. These aspects are also covered in detail in this course.

OBJECTIVES:

  • To compute inductance/capacitance of transmission lines and to understand the concepts of GMD/GMR.
  • To study the short and medium length transmission lines, their models and performance.
  • To study the performance and modeling of long transmission lines.
  • To study the effect of travelling waves on transmission lines.
  • To study the factors affecting the performance of transmission lines and power factor improvement methods.
  • To discuss sag and tension computation of transmission lines as well as to study the performance of overhead insulators.
