Presented a paper this year at the Texas A&M 2014 Conference for Protective Relay Engineers entitled "Improving BES Reliability at Large Generating Station Locations".
Currently awaiting IEEE Power Engineering Society approval for a transaction paper entitled "Rethinking Electrical Power Engineering Education". The paper explores the following three topics associated with electrical power engineering education and is suggested for anyone interested in a deeper understanding of power system fault calculations and three phase ac theory in general.
• Is the per-unit system really more efficient?
• Demystifying ground fault calculations.
• Exploring ac theory at the atomic level.
Is the per-unit system really more efficient? - compares a per-unit short circuit calculation to an ohmic approach with unanticipated results.
Demystifying ground fault calculations – covers a comparison of the sequence impedance per-unit ground fault calculation to an ohmic approach with unexpected results.
Exploring ac theory at the atomic level - describes the author’s quest for an atomic explanation for ac theory using the Bohr model of the atom. Bohr model explanations are commonly provided for dc, vacuum tube, solid-state electronics, chemistry, and physics, but appear to be conspicuously absent for ac theory. This section will present simple Bohr model explanations that cover how ac current can travel at or near the speed of light; why a changing magnetic flux is required to induce a voltage; and what causes atoms to align with magnetic fields.
