Course Objectives:

Number	Objectives
1 Mutual inductance and transformers	Apply Faraday’s law to develop mutual inductance in coupled circuits. Identify current-flux directional relation using dot convention for ideal transformers. Use turns ratio in computing voltages, currents, and powers. Relate electrical characteristics to equivalent circuit, and use circuit in analysis. Identify three-phase transformer connections and their applications.
2 3-phase circuits	Apply per phase analysis in performing power calculations for balanced three-phase circuits using actual and per unit quantities, for both delta- and wye-connected loads. Identify one-line diagram from 3-phase circuit and vice-versa.
3 Synchronous generators	Perform steady state analysis of three-phase synchronous generators using phasor diagrams and the relations between power factor, leading/lagging, excitation level, current angle, reactive power generation, loads, and capacitive versus reactive loads. Identify basic control and feedback concepts related to main electrical control systems.
4 Transmission	Relate electrical characteristics of an overhead transmission line to a lumped parameter, pi-equivalent model; compute power flow across a transmission line, and use the strong coupling between real power flow and angular separation, and between reactive power flow and voltage magnitude, to assess power flow; identify power transfer limitations.
5 Network Analysis	Form the admittance matrix from the network data, obtain the impedance matrix from inversion, and use them to compute nodal current injections from node voltages or vice versa. Develop nodal power injection equations and solution procedure.
6 Distribution	Use two-port networks to perform distribution circuit voltage regulation and efficiency calculations. Perform power factor correction calculations for large industrial loads, and relate to resonance.
7 Optimization	Apply the Kurash-Kuhn-Tucker (KKT) conditions in solving multivariable constrained optimization problems. Solve the economic dispatch problem (a nonlinear equality and inequality-constrained optimization problem) , and identify the economic significance of the LaGrange multipliers.
8 Power Electronics	Identify the current-voltage characteristic for a thyristor, GTO thyristor, MOSFET, and IGBT and their relative speeds and power handling capabilities. Describe applications in AC/DC, DC/DC, and DC/AC conversion circuits.
9 Induction machines	Perform steady-state calculations for induction motor operation in terms of applied voltage, currents, slip, rotational speed, and torque, and identify the relationship between the speed-torque characteristic of the induction motor and a speed-torque characteristic for typical loads. Identify voltage/frequency speed control techniques.
