Course Description and Learning Goals:

Concepts, insights, and development of theory-based intuition are emphasized throughout this course.  This may be one of the first systems-level courses that you've taken. As such, the design and analysis you're doing often has countless variations on a basic theme.  As do professional engineers, focus on grasping basic concepts and intuitively applying them to the specific problem at hand.  Even when analysis appears relatively straight-forward, cookbook or 1-2-3 procedural approaches often fail.  And, most importantly, a design engineer must have an intuitive and conceptual feel for things.

This course provides a broad introduction to a) generation and conversion of electrical energy and b) electrical power systems.  The following gives a you a general idea of the course material.

a) Generation & Conversion of Electrical Energy
The focus is wide-ranging: from photovoltaics (solar energy) to batteries, fuel cells, wind power, transformers, motors, and generators. Applications range from satellites, electric cars, communications installations, aircraft, cars, computers, medicine, and of course the traditional industrial and utility areas.

Motors, generators, and transformers were once thought to be "mature" areas, but there are now many new exciting high-tech advances taking place, surrounding application of power electronics, optimal (re)design of rotating machine technologies, application of new magnetic and dielectric materials, and advanced control strategies. For example, induction motors with variable speed drives have almost completely replaced DC motors in manufacturing facilities. Electric vehicles and other applications depend completely on variable speed drives with either DC motors or AC induction motors.

• Solar Cells and Photovoltaic Generation
• Batteries
• Fuel Cells
• Wind Power
• Phasor Analysis
• Magnetic Circuits, Mutual Inductance
• Transformers
• Magnetic Fields, Induced Voltage, Induced Force
• Induction Motors (Time Permitting - Single Phase induction motors: split phase, capacitive start, etc.) 
• Overview of power electronics, motor drives (sometimes called VFDs or Variable Frequency Drives)
• Synchronous Machines - Generators & Motors
  

b) Introduction to Electrical Power Systems
"Power Systems" exist in many forms.  In addition to the traditional high-voltage "power grid" systems, there are self-contained systems for automotive, shipboard, aircraft, space, etc.  In remote areas or other special applications, there can be stand-alone systems power by wind or solar. 

• Three-phase phasor analysis, including three-phase transformers.
• Per Unit system of calculation
• Safety while working around Electrical Systems
• Power Factor Correction
• Load Factor and Voltage Regulation
• Industrial and utility distribution systems - analysis and design
• Basic distribution system equipment: meters, switches, circuit breakers, fuses, reclosers, sectionalizers, surge arresters
• Distribution substations and system design - layout, cables and lines, introduction of the National Electrical Code, etc.
• Design and operation of Grid Transmission systems - load flow, operation, and planning.
