High Voltage Direct Current Transmission
The massive transmission of electricity in the form of DC over long distances by means of submarine cables or overhead transmission line is the high voltage direct current transmission. This type of transmission is preferred over HVAC transmission for very long distance when considering the cost, losses and many other factors. The names Electrical superhighway…

Load Curve | Load Duration Curve
Load Curve A graphical plot showing the variation in demand for energy of the consumers on a source of supply with respect to time is known as the load curve.If this curve is plotted over a time period of 24 hours, it is known as daily load curve. If its plotted for a week, month,…

Diversity Factor
We can not store electricity. Thus we have to generate electricity when it is required and as much it is required. The electrical source either it is generating station or substation or any other electric utility, has to fulfil the maximum demand of all connected loads to that source. But we are fortunate enough that…

Three Phase System over Single Phase System
Presently 3-ø AC system is very popular and being used worldwide for power generation, power transmission, distribution and for electric motors. Three phase system has the following advantages as compare to single phase system: Power to weight ratio of 3-ø alternator is high as compared to 1-ø alternator. That means for generation for same amount of Electric Power,…

Electrical Power System
What is a Power System? An electric power system is defined as a network of electrical components used to supply, transfer, and consume electric power. The supply is done through some form of generation (e.g. a power plant), the transfer is done through a transmission (via a transmission line) and distribution system, and the consumption…

Electrical Grid System
The connection of several generating stations in a network of particular transmission voltage level is commonly known as electrical grid system. By interconnecting different power generating stations we can solve various difficulties arise in power system. The structure, or “network topology” of a grid can vary depending on the the load and generation characteristics, constraints…

Steam Turbine
The steam turbine is a favourite prime mover in a steam power generating plants. The steam turbine may be of capacity from 5 megawatts 2000 megawatt. The advantages of a steam turbine over a diesel engine are as follows. The size of a steam turbine is much smaller than that of an equivalent diesel engine. The size…

Steam Thermal Power Plant
A thermal power generating plant works based on the Rankine Cycle. There are mainly three primary inputs given to thermal power generating plants for producing electricity. These three most essential elements are coal, air, and water. Coal is used as fuel here because we are going to draw the flow diagram of a coal thermal…

Thermal Power Generation Plant
What is a Thermal Power Plant? A thermal power generation plant or thermal power station is the most conventional source of electric power. The thermal power plant is also referred to as a coal thermal power plant and steam turbine power plant. Let’s dive into how a thermal power plan works. Theory of Thermal Power…

Cogeneration
Cogeneration is also called as combined heat and power or combine heat and power. As it name indicates cogeneration works on concept of producing two different form of energy by using one single source of fuel. Out of these two forms one must be heat or thermal energy and other one is either electrical or…
