Overview

abstract

  • Thesis (M.S., Electrical and Computer Engineering) -- University of Idaho, 2016 | This thesis encompasses two different subjects. The first is the performance of a distance protection scheme along with related supervisory elements are investigated when a shunt connected static synchronous compensator (STATCOM) is tapped to the midpoint of a transmission line. Different fault types are simulated while the STATCOM absorbs reactive power. The results show the distance relays tend to overreach when a STATCOM is injecting inductive current. The second is part of an ongoing microgrid project that is held in a medium sized city in the Pacific Northwest. In this thesis, the microgrid control studies are discussed for a medium sized city in the Pacific Northwest. General information about the microgrid concept and operation are provided. The study focuses on examining the microgrid behavior during varied system conditions. The results of the voltages and frequencies for both the grid and microgrid sides show the effect of the system conditions on the islanding detection schemes.
