Substation 10kV generator

What is a 10 kV full buried box-type substation?

In this paper, a type of 10 kV full buried box-type substation, which consists of buried box, high-voltage power supply system, low-voltage distribution system, transformer and intelligent control system is designed. Above all, the overall design and the key equipment of the full-buried substation are described.

What voltage does a primary substation use?

Usually they use 110 kV or 220 kV voltage level. Generally, a primary substation includes a high-voltage busbar system, medium-voltage busbar system, auxiliary system, and one or several main transformers. In order to provide operational flexibility and to have more than one supply alternative, there might be several incoming radial lines.

What are the different types of power substations?

Depending on the purpose served, power substations might be classified as: Step-up substations – This type of substations steps up the generated voltage to the voltage level, which is used to transmit the electric power. Primary substations – These substations receive the electric power, which is transmitted by three-phase overhead system.

What is a primary substation?

Primary substations in a network are used to step down a high voltage level in order to supply secondary substations by lower voltage. Usually they use 110 kV or 220 kV voltage level. Generally, a primary substation includes a high-voltage busbar system, medium-voltage busbar system, auxiliary system, and one or several main transformers.

Are all substations included in a power supply scheme?

Not all power supply schemes may include all these types of substations, and some of substations could be neglected. Primary substations in a network are used to step down a high voltage level in order to supply secondary substations by lower voltage. Usually they use 110 kV or 220 kV voltage level.

What is a distribution substation?

Distribution substations – This type of substations is constructed not far from consumers. The main function of these substations is to step down the voltage level to three-phase voltage, which is used in distribution network. Figure 1 represents the structure of a power supply system with all mentioned above substations.
