An electrical substation is an assemblage of electrical components including busbars, switchgear, power transformers, auxiliaries etc. These components are connected in a definite sequence such that a Circuit. can be switched off during normal operation by manual command and also automatically during abnormal conditions such as short-Circuit.

Basically an electrical substation consists of number of incoming Circuits and outgoing Circuits. connected to a common Bus-bar systems. A substation receives electrical power from generating station via incoming transmission lines and delivers electrical power via the outgoing transmission lines.

Main tasks associated with major sub-stations in the transmission and ditribution system include following:

• Protection of transmission system.
• Controlling the Exchange of Energy.
• Ensure steady State & Transient stability.
• Load shedding and prevention of loss of synchronism. Maintaining the system frequency within targeted limits.
• Voltage Control; reducing the reactive power flow by compensation of reactive power, tap-changing.
• Securing the supply by proving adequate line capacity.
• Data transmission via power line carrier for the purpose of network monitoring; control and protection.
• Fault analysis and pin-pointing the cause and subsequent improvement in that area of field.
• Determining the energy transfer through transmission lines.
• Reliable supply by feeding the network at various points.
• Establishment of economic load distribution and several associated functions.
