Single Line Diagram Of Power System. The various features of the system are different based on the problem that is considered. Between the generating stations and the distribution stations three different levels of voltage transmission sub transmission and distribution level of voltage are used.
The electrical energy is produced at generating stations and through the transmission network it is transmitted to the consumers. When analysis is done using symmetrical components different diagrams may be drawn that will represent the electric circuitry for positive negative and zero sequence components. Can be described using a standard symbol with three wires instead of three wires in the three phase line.
The high voltage is required for long distance transmission and the low voltage is required for utility purposes.
The circuit breaker transformer capacitor busbar etc. Ats selects between the normal power grid and emergency generator. The various features of the system are different based on the problem that is considered. It is the general procedure to use single line diagrams for representing three phase systems.
