About Us ABET ECE 1769Power Systems Analysis i(3 credits) Description: A first course in modern power system analysis which emphasizes basic concepts. Starting from ac circuit background, phasor notation is used to describe power flow on single/three phase transmission lines. Single-line equivalents are quickly used. The per-unit system is introduced and applied to transformers. Transformers are described from magnetic circuits. Three-phase transformers/autotransformers are analytically described. Simplified per unit equivalents are applied to transformers for power transmission. Analytical equivalents for synchronous generators are developed. Their loading capability is described. Short circuit and transient response of the generators is analyzed. Geometric dimensions and conductor characteristics of three-phase transmission lines are used to determine series reactance and shunt capacitance (line charging). Short length and long length equivalents are developed. Current and voltage relations are derived for transmission lines. Networks of generation, transmission, loads, and compensating devices (capacitor banks, shunt reactors, etc) are studied. Admittance and impedance models of the networks are derived and used for power flow. Power flow on the network using software for Newton-Raphson methods to solve the nonlinear computations. Network short circuit (fault) calculations are used to size circuit breakers. Symmetrical components are introduced to describe unbalanced faults on the network. Pre-requisite: ECE/COE 0041 Linear Circuits and Systems II Text: Grainger and Stevenson, “Power System Analysis”, McGraw-Hill publishers Reference: Glover and Sarma, ”Power System Analysis and Design” Course Objective: To explain to students how power systems operate and to illustrate how basic circuit analysis is applied to real problems. Topics Covered: Complex power, per unit, transformer magnetics, autotransformers, three-winding transformers, synchronous machines, two-axis machine equivalents, series impedance of transmission lines, bundled conductors, parallel lines, capacitance of transmission lines, short and medium length lines, power flow on transmission lines, network admittance computations, coupling, network impedance computations and faults, power flow by Newton-Raphson software, symmetrical components. Class/Laboratory Schedule: There are two seventy-five minutes lectures per week. Professional Component Contributions: Students learn about the current state of power generation and distribution, including political and social as well as technical problems. The responsibility of engineers to society is discussed. Students also gain experience in using the basic theory and analytical tools they have been learning about in their curriculum.
