4 FAQs about The role of AC generator in substation

How does a generating substation work?

These substations receive power from the electrical generators at a lower voltage and sends it to a transmission line at a higher voltage. A generating substation has main components including step-up transformers, circuit breakers, CT, PT, isolators, capacitor banks, and many other auxiliary equipment.

What is a substation in a power system?

A substation is a systematic arrangement of electrical equipment like transformers, circuit breakers, isolators, and more, which is designed and developed to change some electrical parameters like current, voltage, frequency, etc. of the electrical supply. In an electrical power system, a substation is one of the most important parts.

Why is a substation important?

A substation is a crucial part of the electrical generation, transmission, and distribution system. It serves several key functions: Voltage transformation: substations use transformers to step up (increase) or step down (decrease) voltage levels. This is essential for efficient long-distance transmission and safe local distribution of electricity.

What are the components of a generating substation?

A generating substation has main components including step-up transformers, circuit breakers, CT, PT, isolators, capacitor banks, and many other auxiliary equipment. Substations designed for changing the voltage level of electrical supply are called transformer substations.
