Creator:: Agha-Mirsalim, Mojtaba
Abstract:: The doubly-excited machine can be used as a variablespeed generator or as a variable-speed-drive motor. In this thesis the focus is on the aspects associated with generating electric power (real and reactive) from erratic energy resources such as water or wind. In such cases, the power input to the prime...

Creator:: Zhang, Haoran
Abstract:: With the introduction of high speed semiconductor power devices and the increased application of adjustable speed drives (ASDs) for efficient speed control of ac motors, there has been a growing number of costly motor-drive related process failures. It has been found that the high dv/dt and high switching frequency have...

Creator:: Dai, Shaoan
Abstract:: With the development of high performance power electronic and semiconductor technologies, Adjustable Speed Drive (ASD) systems are increasingly applied in residential, commercial and industrial applications. Due to the advantages at higher power ratings, the three-level Neutral-Point-Clamped (NPC) Voltage Source Inverter (VSI) is being employed in industrial and traction applications, static...

Creator:: van Zyl, Annabelle
Abstract:: The awareness of electric power quality has increased over the past decade as electronic equipment has become more susceptible to power disturbances. The most disruptive power disturbances are voltage sags and momentary interruptions and their effect on adjustable speed drives (ASDs) is studied in this thesis. Several solutions have been...

Creator:: Starrett, Michael A.
Abstract:: Recent opportunities for new hydropower generation in the United States have often been in non-powered dams and run-of-river type flows occurring in low-impact natural areas and unregulated conduits. At the same time, a changing water resource paradigm is challenging some existing generation in drought stricken areas where supply reservoirs behind...
