Per Unit Systems for GATE EE: Concepts and Solved Problems

Navigating power system analysis in the GATE Electrical Engineering exam requires a rock-solid grasp of the per unit (pu) system. This text-based course simplifies complex network calculations, helping you convert actual physical quantities into normalized per unit values with speed and accuracy. You will start with foundational definitions of base quantities, learn how to establish a consistent base across an entire power system, and work through structured step-by-step derivations. By reading through clear explanations and studying detailed numerical breakdowns, you will learn to solve the exact types of per unit problems that frequently appear in competitive exams. What you'll learn: - Understand the core concepts and advantages of using per unit systems in power network analysis - Calculate base impedance, base current, and per unit values for both single-phase and three-phase systems - Apply the change of base formula accurately to components like generators, motors, and transmission lines - Analyze three-phase transformer banks and model their per unit impedance diagrams - Practice solving previous exam questions with structured, written step-by-step solutions This course begins with essential terminology, basic electrical relationships, and foundational formulas before moving into complex multi-component networks. Every concept is reinforced with written examples designed to build your problem-solving speed. This course is designed for electrical engineering students and GATE aspirants who want to master power system calculations from the ground up, with no advanced prerequisites required.
