Per-Unit Analysis for Power Systems

Are complex power system calculations overwhelming you? Understanding electrical networks, especially three-phase systems, can be challenging due to varying equipment ratings and voltage levels. This course demystifies the per-unit system, a powerful normalization technique that simplifies the analysis of single-phase and three-phase electrical networks. By mastering this method, you will be able to convert diverse system parameters into a common base, making complex calculations more manageable and intuitive, ultimately enhancing your ability to understand and design stable power grids. What you'll learn: Understand the core principles and benefits of the per-unit system for power system analysis. Apply per-unit conversions to single-phase circuits, including resistors, inductors, capacitors, and transformers. Master the application of per-unit analysis to complex three-phase power systems and unbalanced conditions. Practice calculating impedance, voltage, current, and power in per-unit values across different system components. Develop proficiency in selecting appropriate base values for various sections of a power system. Learn how per-unit representation facilitates fault analysis and stability studies in modern grid environments. The course begins with foundational concepts and the rationale behind per-unit systems, then progresses to step-by-step applications for single-phase and three-phase components. You will work through practical examples and exercises to solidify your understanding of real-world power system analysis. This course is ideal for beginners, including students and aspiring electrical engineers, who want to grasp the fundamentals of power system analysis. No prior experience with per-unit systems is required, only a basic understanding of AC circuit principles. Start your journey to simplified power system analysis today.
