POWER SYSTEM(GTU) BOOKS

             POWER SYSTEM (GTU)

  Hello, my friends. Hope all of you are safe at home and taking proper precautions and getting vaccinated. 

As all the intermediate semesters got the merit-based promotion you all get promoted to the next semesters and some of you may have started purchasing books from markets but if you don't want to go outside you can have soft copies of your books. 

Here we have brought you a pdf book for sem5 ELECTRICAL ENGINEERING,  of" power system". As well as all other subjects pdfs.

Power System

Definition: The power system is a network which consists generation, distribution and transmission system. It uses the form of energy (like coal and diesel) and converts it into electrical energy. The power system includes the devices connected to the system like the synchronous generator, motor, transformer, circuit breaker, conductor, etc.

The power plant, transformer, transmission line, substations, distribution line, and distribution transformer are the six main components of the power system.The power plant generates the power which is step-up or step-down through the transformer for transmission.

The transmission line transfers the power to the various substations.Through substation, the power is transferred to the distribution transformer which step-down the power to the appropriate value which is suitable for the consumers.

Structure of Power System

The power system is the complex enterprise that may be subdivided into the following sub-systems.The subsystems of the power system are explained below in details.

Generating Substation

In generating station the fuel (coal, water, nuclear energy, etc.) is converted into electrical energy. The electrical power is generated in the range of 11kV to 25kV, which is step-up for long distance transmission. The power plant of the generating substation is mainly classified into three types, i.e., thermal power plant, hydropower plant and nuclear power plant.

The generator and the transformer are the main components of the generating station. The generator converts the mechanical energy into electrical energy. The mechanical energy comes from the burning of coal, gas and nuclear fuel, gas turbines, or occasionally the internal combustion engine.

The transformer transfers the power with very high efficiency from one level to another. The power transfer from the secondary is approximately equal to the primary except for losses in the transformer. The step-up transformer will reduce losses in the line which makes the transmission of power over long distances.
