This is the presentation I gave during my 8th sem of Electrical Engineering course at NIT Durgapur. It is here for you guys. Make life easier. Cheers! For more information mail me: sdey.enteract@gmail.com
Basics of electric traction system .
Covering technologies used and their use in Indian railway.
Types of traction systems.
Working basics of various types.
Historical analysis to some extent.
The electricity supply industry is undergoing a profound transformation worldwide. Market forces, scarcer natural resources, and an ever-increasing demand for electricity are some of the drivers responsible for such unprecedented change. Against this background of rapid evolution, the expansion programs of many utilities are being thwarted by a variety of well-founded, environment, land-use, and regulatory pressures that prevent the licensing and building of new transmission lines and electricity generating plants.
Load Frequency Control of Two Area SystemManash Deka
This is a synopsis presentation on a project of designing and analyzing Load Frequency Control (LFC) of a two area system. This is useful for students, basically of Electrical Engineering branch. This project will be simulated in simulink of MATLAB.
What is a Smart Grid?
The Smart Grid Enables the ElectriNetSM
Local Energy Networks
Electric Transportation
Low-Carbon Central Generation
What Should Be the Attributes of the Smart Grid?
Why Do We Need a Smart Grid?
Is the Smart Grid a “Green Grid”?
Alternative Views of a Smart Grid
Infinite bus bar is one which keeps constant voltage and frequency although the load varies. Thus it may behave like a voltage source with zero internal impedance and infinite rotational inertia.

Saudi Arabia stands as a titan in the global energy landscape, renowned for its abundant oil and gas resources. It's the largest exporter of petroleum and holds some of the world's most significant reserves. Let's delve into the top 10 oil and gas projects shaping Saudi Arabia's energy future in 2024.
5. Evolution
• Started in 1853 AD
• 1920 : Nationalisation
• 1925-1932: Electrification
• 1957 : Adoption

6. Electric Traction Systems
• Tractive force coming from electric motors
• Electric traction is considered to be an advanced
traction system and the most efficient of all other
traction systems such as Steam and Internal
Combustion (IC) engine type systems etc.
