## Description

This course aims to teach you the fundamentals of power system analysis, making tedious calculations in power system studies easy to understand for you. As we all know a power system comprised of heavy equipment needs to be analyzed properly under all operating conditions. In order to make the analysis methodologies easy to calculate and simple, I will teach you how power systems can be simplified more by incorporating per unit systems. Furthermore, you will learn how the tedious formulas of the per-unit system can be used to evaluate power flow study.

I will also introduce you to the term power factor along with a detailed discussion on the advantages and methods to select the proper size of power factor correction equipment. Then, I will start building your concept from the very basic explanation of balanced three phase power and important principles for balanced system. By the end of this part, you will have a strong idea on the significance of balanced three phase power.

Once you are familiar with the basics of balanced three-phase power, I will introduce you to the power flow concepts including understanding and solving power flow equations using Newton Raphson and Ybus admittance matrix. By the end of this module, you will learn how the power flow equations can be solved easily without any high consumption of time.

I have been creating high quality video tutorials about Power Systems since 2015 and focus specifically on the fundamentals. It is dedicated to the people who make power and energy work and make sure that Power Systems are safe, reliable, operable, protected and well designed. But it takes time and money to continue delivering high quality video tutorials. My goal is incredibly simple. I want to make Power Systems Intuitive, Open and available to everyone, everywhere. Your purchase will allow me to keep making valuable technical videos and keep the doors of knowledge open to everyone.

See you on the other side. Thank you and take care.
