Abstract

This paper presents a lecture note of pu method for power system analysis. The author tries to help students in class better understand the fundamental of pu calculation using a very simple DC circuit. And a voltage drop calculation by pu method for a distribution system is given to help understand the importance of the vector reference in AC circuit analysis. A short current calculation by pu method for a power system with a generator, transformer and transmission line is also presented to show how pu calculation can be applied to real power systems, in which all the data are the ones currently being used by KEPCO and other industrial sites.
