What kind of generator is good for substation

Generating substations step up the voltage from the generator's lower voltage to a higher voltage which is more economical for transmitting electric power over longer distances with less power losses caused by the impedance of transmission lines.

There are different types of power generating substations like thermal, atomic, and hydro-electric. Based on the availability of different resources, substations are building at different locations, but these locations may not be closer to load centers. The actual power utilization can be done by the load center.

Substation are used to transform the voltage with power transformer. From low voltage to high voltage at the power plant with breaker and control system to be able to transport the energy, and other substation at the arrival to decrease the voltage.

To fulfill the function of a substation, they include a wide variety of equipment. Each of them will be explained in the next subsections. Power transformers are the most important equipment in an electrical substation. They are different from distribution transformers. They perform different functions. They are used to

For the most part, electric power substations are viewed as the most integral part of a power utilities' electric system, with electric systems being comprised of power generation, transmission, and distribution systems. (See A Basic Explanation Summary of How the Electric Power Grid Works)

The substations contain power transformers that reduce the voltage from sub-transmission levels to distribution levels, usually in the range of 4.16Y/2.4 kV to 34.5Y/19.92 kV. The transformers are normally equipped to regulate the substation bus voltage.
