1st Edition
Advanced Topics in Power Systems Analysis Problems, Methods, and Solutions
Electric Power Systems Analysis" is one of the most challenging courses of the Electric Power Engineering major which is taught for junior students. Its complexity arises from numerous prerequisites, a wide array of topics, and a crucial dependence on computational tools, presenting students with significant challenges."
This book serves as a continuation of our previous book, "Fundamentals of Power System Analysis 1, Problems and Solutions", specifically delving into advanced topics in power system analysis.
The structure of the "Advanced Topics in Power Systems Analysis" is as follows:
"Economic Load Dispatch", "symmetrical and unsymmetrical short circuits", "Transient Stability Analysis", "Power system linear controls" and "Key Concepts in Power System Analysis, Operation, and Control".
The structure of the "Fundamentals of Power System Analysis 1" is as follows:
"Introduction to the Power System", "Transmission Line Parameters", "Line Model and Performance", "Power Flow Analysis"
In brief, advantages associated with delving into both books are:
· A variety of tests to prepare for employment exams.
· Electrical engineers practicing power system analysis can find almost everything they need.
· This book contains both difficult and easy problems and solutions.
· Readers have the capability to solve problems presented in this book solely using a calculator, without dependence on computer-based softwares.
· This book provides power systems concepts through studying two-choice questions.
In the end, we had a great time in writing this book, and we truly hope you enjoy reading it as much as we enjoyed creating it!
