**Course Structure:** The class meets for two lectures a week, each
consisting of two 50-minute sessions. There is weekly homework due and a final
project. The course includes a field trip to a local utility facility.

**Computer Resources:** Homework and software project can be done on a PC
using C or C++ language.

**Grading:** Homework 25%, Final Project 25%, Midterm Exam 25%, Final Exam 25%.

**Outcome Coverage:**

(a) *An ability to apply knowledge of mathematics, science, and
engineering.* This course has an extensive component of distribution system
modeling and analysis. Mathematical models of distribution system components
are integrated into a system. Students are asked to use circuit analysis
techniques to calculate the voltages, currents, and power flows on a
distribution feeder. Distribution system power flow algorithms are iterative
numerical methods developed for the power flow problems. (M)

(c) *An ability to design a system, component or process to meet desired
needs within realistic constraints such as economic, environmental, social,
political, ethical, health and safety, manufacturability and sustainability.*
Students are required to learn the protective device characteristics and
coordinate the settings of multiple devices on a distribution feeder. With the
instructor's approval, students can select a final project that involves an
important design task for distribution systems. The project requires an
extensive level of effort and report writing. (H)

(e) *An ability to identify, formulate and solve engineering problems.*
The class includes various examples of power system operational problems such
as feeder overload and voltage violations. Students are asked to identify
problems from the system operating conditions (e.g. low voltage profiles) and
develop solutions such as capacitor placement on a feeder. In the final project,
the students are asked to survey the state of the art and identify critical
engineering problems associated with their project. (H)

(g) *Ability to communicate effectively.* Two written reports are
graded on the written presentation of their ideas as well as on the technical
content. The first is a one-week homework assignment on a contemporary issue
concerning the distribution of power. The second is the report for the final
project, a rather extensive project in which they must design a method and
software to solve the general power flow problem in a radial, multi-branch
system. About 30% to 40% of the project grade depends on report organization
and clarity. (H)

(h) *The broad education necessary to understand the impact of engineering
solutions in a global and societal context.* This course includes
discussions on the recent regulatory reform of the power industry throughout
the world. This class also has a component on the characteristics of load for
industry, commercial and residential users. (M)

(k) *An ability to use the techniques, skills, and modern engineering
tools necessary for engineering practice.* Students use a state-of-the-art
software programming tool for the distribution power flow project. The
state-of-the-art of distribution automation tools is discussed in class. (M)
