Title :
The whys of distribution system analysis
Abstract :
Why do electrical engineers perform distribution system planning studies? Why are unbalanced studies needed? Why should distribution lines be modeled as non-transposed? Why is phasing of the distribution lines and loads important? Why are power losses important and how are they computed? Why is power factor measured at the substation important? Why is power factor of the loads important? Why is it necessary to know the exact connection of three-phase transformer banks? Why are symmetrical components not used in distribution system analysis? Why should an induction motor not be modeled as a constant PQ load? Why use R and X setting on tap changing voltage regulators? New engineers entering the electric utility industry should know the answer to all of these questions. This paper will present the “textbook” answers.
