Basic Layout And Working Of A Thermal Power Plant
Layout diagram of electrical energy from generation to distribution. The substation receives electrical energy directly from generating stations through incoming power supply lines while it delivers electricity to the consumers through outgoing transmission lines. Central station where power is generated by 3 phase alternators. A substation which is near to the electrical power generation is also known. Figure 1 single line diagram of transmission and distribution network. In figure 1 cs. Represents the central station where power is generated by 3 phase alternators at 66kv or 11kv or 132kv or even 32 kv.
Distribution substation typically operates at 24 345 kv voltage levels and deliver electric energy directly to industrial and residential consumers. Electric power distribution is the final stage in the delivery of electric power. Power system restoration outage voltage collapse switching programs therefore the generation of electrical energy is happening simultaneously as we use it. A substation is a part of an electrical generation transmission and distribution system. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kv and 35 kv with the use of transformers. Single line diagram of power supply system the electrical energy is produced at generating stations and through the transmission network it is transmitted to the consumers.
In addition our demand is always varying. It carries electricity from the transmission system to individual consumers. Between the generating station and consumer electric power may flow through several substations at different voltage levels. Therefore the generation is also varying with it. Primary distribution lines carry this medium voltage power to. These feeders serve a large number of premises and usually contain many branches.
The electricity substation is a network of electrical equipment which is connected in a structured way in order to supply electricity to end consumers. Substations transform voltage from high to low or the reverse or perform any of several other important functions. Apart from varying demand the type of current we consume also varies. There is numerous electrical substation components like outgoing and incoming circuitry each of which having its circuit breakers isolators transformers and busbar system etc for the smooth functioning of the system. Electrical bus system and electrical substation layout july 25 2018 february 24 2012 by electrical4u there are many different electrical bus system schemes available but selection of a particular scheme depends upon the system voltage position of substation in electrical power system flexibility needed in system and cost to be expensed. Distribution feeders transport power from the distribution substations to the end consumers premises.
Between the generating stations and the distribution stations three different levels of voltage transmission sub transmission and distribution level of voltage are used. The voltage is then stepped up by suitable 3 phase transformers for transmission purposes.
