Power Systems II

Description

This course provides students with the knowledge and analytical tools to study power system faults, transients, and stability. Topics include transients in R-L circuits, internal voltages of loaded machines under fault conditions, and fault analysis using the Z-bus method. Students will learn the principles of circuit breaker selection, symmetrical components, and sequence networks for machines and transformers. The course also covers unsymmetrical faults (single line-to-ground, line-to-line, and double line-to-ground), as well as system stability analysis using the swing equation, power angle equation, and the equal-area criterion, complemented by numerical methods for stability evaluation.
