Substation Components And Their Functions Ppt

A substation is a high voltage electrical system which serves as a link between the generating station and the distribution system. It steps down the high voltage to a level which can be handled by the distribution system. A substation performs many functions such as voltage transformation, switching, metering, protection and control.

Let us discuss these functions in detail: Voltage Transformation: The primary function of a substation is to transform voltages from one level to another. For example, a generating station may have an output of 11 kV but the distribution system may use 220 V. In such cases, transformers are used to step down the voltage so that it can be safely used in homes and offices.

Switching: A substation also acts as a switchyard where circuits are switched on or off. This is done using circuit breakers and switches. Circuit breakers are used to protect equipment from damage due to sudden surges in voltage while switches are used to manually control the flow of electricity.

Metering: A substation houses various kinds of meters which help in monitoring the flow of electricity. These meters measure parameters such as current, voltage, power etc. Metering helps in detecting any abnormalities in the electrical system so that corrective action can be taken promptly.

Protection: Another important function of a substation is protection. Substations contain devices which protect equipment from damage due to faults or overloads. These devices include fuses, circuit breakers and relays.

Fuses provide protection against overcurrent while circuit breakers provide protection against both overcurrent and undervoltage conditions. Relays are used for remote operation of circuit breakers and for providing automatic protection against faults..

Control: Control panels located inside substations allow operators to monitor and control the flow of electricity through different circuits..

Substation Equipment Ppt

Substation equipment is critical to the functioning of electric power systems. A substation typically includes high-voltage switchgear, transformers, and other equipment needed to connect transmission lines and distribute power within a defined area. The type and size of substation equipment varies depending on the voltage level of the system and the specific needs of the utility or end user.

Switchgear is used to control, protect, and isolate electrical equipment. It consists of disconnect switches, fuses, circuit breakers, and other components mounted on an enclosure. Switchgear must be able to withstand the forces generated by short-circuits without damage.

Transformers are used in substations to step down voltages from high-voltage transmission lines for distribution to customers or for further transmission at lower voltages. Substations may also include capacitors and reactors that are used to improve power factor or regulate voltage. Protective relays are another important component of substation equipment.

These devices monitor conditions on electrical circuits and automatically take action if an abnormal condition is detected that could cause damage to equipment or disrupt service. Communication systems are also often installed in substations so that operators can remotely monitor conditions and control equipment if necessary.

Types of Substation Pdf

Types of Substations Pdf Substations come in a variety of shapes and sizes. Their function is to take high-voltage electricity from the grid and lower the voltage so it can be used by consumers.

The type of substation you need will depend on the voltages involved, the amount of power required, the geographical location, and other factors. Here are some common types of substations: • Step-down substations: These are the most common type of substation.

They consist of transformers that lower the voltage so it can be used by homes and businesses. Step-down substations are usually located near population centers. • Step-up substations: These substations raise the voltage so it can be transmitted over long distances without losing power.

Step-up substations are typically located in rural areas. • Load shedding substations: These substations help prevent blackouts by automatically disconnecting parts of the grid when demand is high. Load shedding substATIONS are usually located near power plants or other major sources of electricity.

What are the Major Equipment at Substation?

A substation is a crucial part of the electrical grid. It serves as a hub where power can be generated, distributed, and controlled. The major equipment found at a substation includes:

-Transformers: These devices convert high-voltage electricity into lower voltages or vice versa. -Circuit breakers: These are used to protect equipment from damage caused by overloads or short circuits. -Capacitors and reactors: Capacitors store energy while reactors help regulate the flow of current.

-Bus bars: Bus bars are made of metal and conduct electricity between different parts of the substation. -Protective relays: Protective relays monitor conditions within the substation and automatically activate circuit breakers in case of an emergency.

What are the Three Types of Substations?

A substation is an electrical installation where the high voltage transmission system connects to the low voltage distribution system. Substations come in a variety of sizes and shapes, but all have three common components: transformers, switchgear, and control equipment. Transformers:

The primary function of a substation transformer is to change the voltage level of electricity so that it can be used by homes and businesses. A typical substation will have several transformers that step down the voltage from 115 kV or 138 kV to a lower level like 12 kV or 34.5 kV. The secondary winding of the transformer is connected to the distribution grid which powers our homes and businesses.

Switchgear: The switchgear controls the flow of electricity through the substation by opening and closing breakers (circuit breakers). The switchgear also protects equipment in the substation from damage caused by faults (short circuits) in the electrical system.

When a fault occurs, circuit breakers open to isolate (disconnect) the section of line where the fault occurred so that repairs can be made without interrupting service to other customers on the grid. Control Equipment: Substation control equipment includes relays, meters, and sensing devices that monitor conditions in the substation and send information back to a control center.

This information is used by operators at the control center to make sure that electricity is flowing safely and efficiently through the substation and on to customers who need it.
