What is Substation ?

Substation is an Electrical installation where power is

controlled for transmission & distribution purpose.

Substations can be categorized as:

Power evacuation substation

Substation part of Transmission system

Substation part of Distribution system

Switching Substation

Distribution Substation


4/80

4



Power Evacuation Substation Located adjacent to the Power Plant

Preferred voltage level

420 kV 245 kV

123,145 kV

72.5, 66 kV

Evacuation voltage level depends on Quantum of power to be evacuated (size of power plant)

Distance of Transmission

Gird network voltage of surrounding transmission system Normally built by

Utilities (e.g. NTPC, NHPC, Captive Power Plant by industries)

Independent Power Producer (IPP)


5/80

5



Transmission Substation Location is decided based on Transmission Grid Network


420kV 245kV

145kV

Transmission voltage depends on Quantum of power to be received / transmitted

Length of transmission line

Normally built by

Utilities (e.g. Power Grid, State Electricity Boards)


6/80

Distribution Substation Location is near the load


245kV 145kV

72.5/36 kV

Station voltage level depends on Demand of power

Utility norms of distribution

Normally built by

Utilities (e.g. State Electricity Broads) Industries

What is Busbar Configuration ?

Busbar configuration or Bus switching scheme is the circuitadopted for substation based on following: System reliability

Operational flexibility

Ease of maintenance

Limitation of fault level Simplicity of Protection system

Ease of extension

Availability of Land

Cost

Various Busbar ConfigurationSingle Bus Scheme

Application

Industrial stations with voltage level generally up to 145kV Also used for 245kV station with 2/3 bays

Features Simple system

Ease of Operation & maintenance

Single level bus layout

Very simple Control & Protection philosophy

Large saving in space

No redundancy
