Outcome Coverage:

A (M) An ability to apply knowledge of mathematics, science, and engineering. This course has an extensive component of power system modeling and analysis. Mathematical models of power system components are integrated into a system. Students use circuit analysis techniques to calculate the voltages, currents, and power flows in a power system. Students are asked to use numerical algorithms to solve the power flow problems. Basic optimization techniques are needed to determine the economic dispatch of a power system.

C. (M) 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. In the computer projects, students are asked to formulate the operating constraints, calculate the operating values of the system, determine if the system meets the operating limits and identify the remedial actions. Students use a power flow program in the design process. Students also design a MATLAB program to calculate the transmission line parameters for various line configurations.

E. (H) An ability to identify, formulate and solve engineering problems. The class includes various examples of power system operational problems such as system overload and voltage collapse. Students are asked to identify problems from the system operating conditions. Students have to formulate the power system model and find the network solutions to determine if the system operating values meet the constraints. Homework problems require the students to identify the proper models and calculation techniques for power system problems.

G. (H) An ability to communicate effectively. Students submit extensive written reports on their computer projects.

H (M) The broad education necessary to understand the impact of engineering solutions in a global and societal context. This course includes 2 hours of discussion on the recent regulatory reform of the power industry throughout the world. The implication of a competitive electricity market on the society as a whole is discussed. Whenever appropriate, students are asked to evaluate the impact of the new electricity market structure on the analytical methods.

K. (H) An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. A state-of-the-art power flow software package is used for the power flow problems. MATLAB tools are used for calculations of the transmission line parameters. Students also use modern numerical techniques for power flow analysis and economic dispatch.

M. (H) Knowledge of differential equations, linear algebra, complex variables and discrete mathematics. The students' work requires concepts and techniques involving differential equations, AC circuit analysis, numerical methods for the solution of nonlinear equations, and solution of the matrix equations.
