Electrical Bus System and Electrical Substation Layout

There are many different electrical bus system schemes available but selection of a particular scheme depends upon the system voltage , position of substation in electrical power system, flexibility needed in system and cost to be expensed. The Main Criterias to be Considered During Selection of one

Electrical Power Substation Engineering and Layout

Electrical Substation Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro-electric, thermal or atomic. Depending upon th

High Voltage Direct Current Transmission | HVDC 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, lo

Load Curve | Load Duration Curve | Daily Load 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, or a year, then

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 for

Why Do We Use 50 Hz or 60 Hz Frequency for Power Systems?

A power system is a network of electrical components that generate, transmit, and distribute electricity to end users. The power system operates at a certain frequency, which is the number of cycles per second of the alternating current (AC) voltage and current . The most common frequencies used for

Auto Reclosing Scheme of Transmission System

The extra high voltage transmission lines transmit huge amount of electric power . Hence, it is always desirable that the continuation of power flow through the lines should not be interrupted for a long time. There may be a temporary or permanent fault in the lines. Temporary faults get automatical

Electrical Power System: What is it? (Power System Basics)

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

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
