Electric Power Plant

A substation is a key part of an electrical power system, acting as a switching and transforming center for electricity. It facilitates the safe and efficient delivery of power from generation sources to consumers. Substations manage voltage levels, connecting different parts of the power grid.
Here’s a more detailed explanation:
Key Functions:
Voltage Transformation: Substations transform voltage levels (either stepping up or stepping down) to match the requirements of transmission and distribution networks.
Switching: They connect and disconnect different parts of the electrical grid, allowing for maintenance, repairs, and rerouting of power flow.
Protection: Substations include equipment like circuit breakers and fuses to protect the grid from faults and overloads.
Control: They provide a central point for monitoring and controlling the flow of electricity.
Interconnection: Substations can connect different voltage levels of the grid, allowing for the flow of power between transmission and distribution systems.
Power Factor Correction: Some substations include equipment to improve the power factor of the electrical system, enhancing efficiency.
Conversion: Some substations convert AC (alternating current) to DC (direct current) or vice versa, which is necessary for certain applications like high-voltage DC transmission.  Types of Substations: Substations can be classified by voltage levels, such as:
Super High Voltage Substations: >500kV.
High Voltage Substations: 66kV, 110kV, 220kV, and 500kV.
Medium Voltage Substations: 6kV, 10kV, 15kV, 22kV, and 35kV.  Location and Ownership: Substations can be found near power plants, on the periphery of consumption areas, or within buildings for space-saving.  They can be owned and operated by utilities or by large industrial or commercial customers.  Importance: Substations are essential for the reliable and efficient operation of the electrical grid, ensuring a continuous and stable supply of electricity to consumers.  Substation – Wikipedia * A substation is a part of an electrical generation, transmission, and distribution system.
