Principles of Power Systems V.K. MEHTA

"Principles of Power Systems" by V.K. Mehta (often co-authored with Rohit Mehta) is a highly regarded and widely used textbook for electrical engineering students. It provides a comprehensive overview of the fundamental concepts and practical aspects of electric power systems.

Here's a breakdown of what the book typically covers:

Generation of Electrical Energy: This section introduces various types of power generating stations, including thermal, hydro, nuclear, and renewable energy sources, along with their operational principles and site selection criteria.
Economics of Power Generation: Topics like load curves, load factor, diversity factor, and tariffs are discussed to understand the economic considerations in power system operation.
Transmission and Distribution Systems:
- Overhead Transmission Lines: Detailed analysis of line parameters (resistance, inductance, capacitance), performance of short, medium, and long transmission lines, voltage regulation, and efficiency.
- Underground Cables: Construction, insulation, and types of underground cables, along with dielectric stress and grading.
- DC and AC Distribution: Principles and calculations for different types of DC and AC distribution systems, including ring main, radial, and interconnected systems.
Voltage Control: Methods for controlling voltage in power systems to maintain stable operation.
Switchgear and Protection:
- Circuit Breakers: Types, operation, and applications of various circuit breakers (oil, air blast, SF6, vacuum).
- Fuses: Types and characteristics of fuses.
- Protective Relays: Principles of operation and types of relays used for protecting power system components (e.g., overcurrent, differential, distance relays).
- Protection of System Components: Specific protection schemes for alternators, transformers, busbars, and transmission lines.
- Protection Against Overvoltages: Discusses lightning and switching surges, and methods for surge protection.
Fault Analysis: Symmetrical and unsymmetrical fault calculations, including the use of symmetrical components for analyzing unsymmetrical faults.
Substations: Layouts, equipment, and types of substations.
Neutral Grounding: Importance and methods of neutral grounding in power systems.
