Power and energy systems
This area of electrical engineering focuses on devices and systems that process and deliver electric energy. It includes the broad topics of electromechanics, design and operation of large electric power and energy systems, magnetic and electric energy conversion methods, the application of electronic devices at high power levels, and alternative energy. Courses in this area cover concepts such as renewable electric energy systems, electric machines, power transmission and distribution, transformers, electronic motor controllers, and switching power converters. The physics of these devices as well as their mathematical models are studied and used to predict the behavior of the devices and to design systems that use them. Other courses in the area examine the overall performance of large systems. An example is the electric power system in North America, which consists of billions of power devices, and which must be analyzed and controlled for safe, consistent, reliable operation under all possible conditions. Operators of large power systems need tools to explore "what if..." questions and then plan to react in cases of failure. This is called reliability assessment. Additional applications of devices and electromagnetic fields are studied in advanced courses. Solar electric panels, hybrid cars, electronic motor controllers, computer power supplies, and backup power units are common applications of power electronics. Rapid advances in computer technology have made it possible to apply parallel processing techniques to large system simulation. The development and integration of renewable energy sources such as wind and solar are producing broad challenges and opportunities. The fast pace of change will continue to challenge engineers in this field.
Potential employers for graduates with an interest in this area include operators and builders of large power systems, such as electric utilities and large engineering consulting firms; manufacturers of power equipment, including wind turbines, motors, and power supplies; manufacturers and users of power semiconductors and other power electronics equipment including solar photovoltaic systems; manufacturers and users of robots, electronic controls, and transportation equipment; and industries which are large electricity consumers, such as the metals industry, automobile industry, oil industry, data industry, and others. These major industries dominate the global economy.
Courses in the Power and Energy Systems area cover the analysis concepts and devices of electromechanics, large electric power and energy systems, magnetic and electric energy conversion, and the application of electronic devices at high power levels.
