Modeling, Analysis and Estimation of Three Phase Unbalanced Power Network

This course focuses on understanding and analyzing modern power systems where loads are no longer perfectly balanced. Traditionally, transmission networks were studied assuming balanced three-phase loads, but this assumption is becoming inaccurate due to electric railways, electric vehicles, and other power-electronic based loads. The course introduces the fundamentals of unbalanced three-phase power systems in a clear and practical way. Students will learn how to model transmission and distribution networks under unbalanced conditions. Different types of unbalanced loads and their impact on voltages, currents, and power flow will be explained. The course covers analysis techniques suitable for real-world unbalanced networks. Quasi-steady state behavior of unbalanced systems will be discussed with practical examples. Methods for estimating system states under unbalanced conditions will be introduced. Emphasis is given to realistic power system operation rather than ideal assumptions. By the end of the course, learners will be able to analyze and understand modern unbalanced power networks confidently.
