What is a substation in a power transmission system?
• SUBSTATION - A station in the power transmission system at which electric power is transformed to a conveniently used form. The station may consist of transformers, switches, circuit breakers and other auxilliary equipment.
What is electric power substations engineering?
Combining select chapters from Leonard Grigsby’s The Electric Power Engineering Handbook with several not found in the original work, Electric Power Substations Engineering has become a widely popular volume on the theory, design, analysis, operation, and protection of power substations.
What are the functions of a substation?
Substations have some additional functions. • BUSBAR (or bus, for short) – is a term we use for a main bar or conductor carrying an electric current to which many connection may be made. • CIRCUIT BREAKER – is used to interrupt circuits while current is flowing through them.
Why is energy storage important?
Energy storage systems absorb the excessive energy when generation exceeds predicted levels and supply it back to the grid when generation levels fall short. Electric Storage technologies can be utilized for storing excess power, meeting peak power demands and enhance the efficiency of the country’s power system.
What is a generating station?
The station may consist of transformers, switches, circuit breakers and other auxilliary equipment. Its main function is to receive energy transmitted at high voltage from the generating station, by either step-up or step-down the voltage to a value appropriate for local use and provide facilities for switching.
What is the difference between transformer substation and industrial substation?
Performance such that no system disturbances are introduced by its operation. Transformer substation:In this type of substation,electrical power is received at one voltage and it is converted to the required voltage. Industrial substation:power required for big industrial estates is received from this substation.
