The Energy Epoch Starts Now
Published in H. B. Glushakow, Energy Miracles, 2022
MIT is the world’s number one engineering institution. It was MIT, in 1882, that established the world’s first electrical engineering program in its Physics Department with a curriculum heavily oriented toward power engineering. At that time, power engineering was a crusading, pioneering part of electrical engineering that included such things as Michael Faraday’s discovery of electromagnetic induction, the design and construction of new types of DC and AC power stations, generators and transformers. Today, MIT’s Electrical Engineering curriculum is found in its Department of Electrical Engineering and Computer Science (EECS). Its EE program is introduced in terms of robotics, communication networks, medical technologies, and interconnected embedded systems. EE courses include circuits and electronics; signals, systems, and inference; nano electronics and computing systems; electromagnetics and applications; electromagnetic fields, forces, and motion; and cellular neurophysiology and computing.
Power System Fault Analysis
Published in A. P. Sakis Meliopoulos, Power System Grounding and Transients, 2017
The symmetrical component method has been widely accepted and used in electric power engineering. However, its applicability is limited to power system analysis problems for which the assumption of symmetric three-phase systems is acceptable. For many analysis problems such as short-circuit analysis, power flow analysis, transient stability, and so on, this assumption has been widely accepted. For other applications, such as analysis of general multiphase networks or three-phase networks with single- and two-phase taps, the symmetrical component method becomes cumbersome. For the purpose of computing fault current distribution and ground potential rise, the symmetrical component method becomes very complex and thus unattractive. An alternative approach is based on the admittance matrix representation of power system elements. We refer to this method as direct phase analysis. The method is simple and able to account for (a) asymmetries of power system elements (i.e., untransposed lines, etc.), (b) single- or two-phase systems, and (c) general multiphase systems. On the other hand, the method is computationally intensive.
The Per-Unit System
Published in Leonard L. Grigsby, Power Systems, 2012
Finally, the reader is advised that there are many scaling systems used in engineering analysis, and, in fact, several variations of per-unit scaling have been used in electric power engineering applications. There is no standard system to which everyone conforms in every detail. The key to successfully using any scaling procedure is to understand how all base values are selected at every location within the power system. If one receives data in per-unit, one must be in a position to convert all quantities to SI units. If this cannot be done, the analyst must return to the data source for clarification on what base values were used.

Sensitivity analysis of a single phase to ground fault system in connection with high impedance faults: A case study

The IEEE power system relaying committee working group D15 (PSRC WGD15) report (Tengdin et al., 1996) stated that HIFs on the distribution system created a unique challenge for protection engineers. This was a status report in 1996. A much earlier IEEE Power Engineering Society (PES) publication (IEEE Power Engineering Society, Downed Power Lines, 1989) from 1989 explained why downed conductors in electric power lines could not always be detected.
