"Modern Power System Analysis " by D.P. Kothari and I.J. Nagrath is a definitive textbook for electrical engineering students and professionals. It covers the modeling, control, and analysis of large-scale power systems.Core Topics Covered
The book is structured to guide readers from foundational concepts to advanced system operations:Modern Power System Analysis by Nagrath Kothari.pdfIntroduction to Power Systems : The book provides
Protection and reliability
Protective relaying: detection of faults and initiation of corrective actions; coordination of relays and breakers to isolate faults with minimal disruption.
Reliability indices: system adequacy and security metrics (SAIDI, SAIFI, loss-of-load probability) guide planning and investment.
Q1: Is the 2nd edition of Kothari sufficient for the GATE exam?
A: Largely, yes. However, GATE 2020+ has introduced questions on FACTS devices and Wide Area Measurement Systems (WAMS), which are better covered in the 3rd edition.
Step 4 – Practice Problems
This book has end-of-chapter problems with answers to odd-numbered ones.
Try to solve using manual calculation first, then verify with software like MATLAB/Simulink or PSAT.
c) Print + Digital Bundles
Some second-hand bookstores include a CD-ROM with the PDF (older editions).
Using the "method of symmetrical components" (Fortescue's theorem), Kothari teaches how to calculate short-circuit currents for:
Single Line-to-Ground (SLG)
Line-to-Line (LL)
Double Line-to-Ground (DLG)
3. Capacitance of Transmission Lines
Electric Field of a Long Straight Conductor
Potential Difference between Two Conductors
Capacitance of a Two-Wire Line
Capacitance of a Three-Phase Line
Effect of Earth on Capacitance
Bundled Conductors and Capacitance
2. Transmission Line Parameters (Chapter 3)
From calculating resistance at DC versus AC (skin effect) to complex inductance calculations for bundled conductors, this section is vital for line design.
