Power Network Analysis
Prof. Abheejeet Mohapatra · IIT Kanpur
About
This course is relevant for third year and final year undergraduate students of Electrical Engineering. After completion of this course, a student will be aware of the basic aspects and tools used in the steady-state analysis, stability and protection of power networks. This course also discusses the recent trends and challenges in modern networks or smart grids analysis due to Renewable Energy Resource integration. Distinct tools for steady-state, transient, and sub-transient analysis for power networks are discussed.
Intended audience: EE Third Year and Final Year BTech Students
Prerequisites: Basic network analysis and machines
