How is a substation designed?
Substations are the points in the power network where transmission lines and distribution feeders are connected together through circuit breakers or switches via busbars and transformers. The first step in designing a power substation is to design an earthing and bonding system.
What is switchyard in electrical?
Switchyard is a switching station which is the main link between the generating plant and the transmission system. It can be considered as the heart of the power plant, the generated power will only be worthy if it can be transmitted and received by the consumers.
What is layout of substation?
In allocating the area of substation, it is to be noted that the flow of electric power is from supply company’s meter room to HV room, then to transformer and finally to the MV switchgear room.
What are the components of substation?
All in all an electrical substation comprises of the following components:
- Lighting arresters.
- Instrument transformers.
- Electrical power transformers.
- Circuit breakers.
- Bus bars.
Is switchyard and substation same?
is that substation is a site where electricity supplied by long-distance (high-voltage) transmission lines is transformed and/or regulated for local (low-voltage) distribution while switchyard is part of a railway with an arrangement of switches (or points) allowing trains to be diverted and reassembled.
What is a substation electrical engineer?
Substation electrical engineers are engineering professionals who design medium and high voltage substations that are used to transmit and distribute electricity. They must review design drawings and perform load analysis to select the overall platform’s power requirements.
What is single line diagram of substation?
The single line diagram (SLD) is the most basic of the set of diagrams that are used to document the electrical functionality of the substation. Typically, single line or one line diagrams are used to document the configuration of the electrical high voltage circuit of a substation.
