The cost of conductor material required for designing a transmission line is a very considerable part of the total cost of a transmission line. Therefore, the determination of proper size of the conductor for the transmission line is very important. The proper size of the conductor for transmission line is ... Read More

Depreciation of Power Plant EquipmentThe reduction in the value of the equipment and other property of the power station every year is known as depreciation. Therefore, a suitable amount, called depreciation charge, must be set aside annually so that by the time the life span of the power plant is ... Read More

Overhead DC Transmission SystemThe overhead transmission system is the one in which the conductors are hanged with the help of pole supports. When the transmission lines carry direct current, then the system is called the DC transmission system.There are three types of overhead DC transmission systems viz. −Two wire DC ... Read More

Two Phase AC Transmission SystemWhen the transmission system consists of two line conductors for the transmission of AC electric power from generating station to the substations for its distribution, it is called the two phase AC transmission system.Depending upon the number of conductors used, the two phase AC transmission system ...

Power Plant or Power StationA power plant or power station or generating station is an industrial facility for the generation of electrical power.A typical generating station or power plant consists of a prime mover (ex. steam turbine, water turbine, etc.) which is coupled to an alternator. The prime mover converts ... Read More

Load CurvesThe graph which shows the variation of load on the power station with respect to time is called the load curve of the power station.The load on a power station does not remain constant; it changes from time to time. These changes in the load on a power station ... Read More

The thermal power plant is a generating station which converts the heat energy of coal combustion into electrical energy. The block diagram of a typical thermal power plant is shown in the figure below.The thermal power plant works on the Rankine cycle. In the thermal power plant, the steam is ... Read More

The function of an electrical power system is to connect the power generating station to a large number of consumers by means of interconnected system of transmission and distribution networks.Therefore, a typical electrical power system has three main parts, viz. −The power generating station, The transmission systems, andThe distribution systems.The ...

A nuclear power plant is a generating station which converts nuclear energy into electrical energy. The schematic diagram of a typical nuclear power station is shown in the figure. It mainly consists of the following parts −Nuclear ReactorHeat ExchangerSteam TurbineAlternator (or Electric Generator)Nuclear ReactorThe nuclear reactor is an apparatus in ... Read More

A power generating station which converts heat energy of the nuclear fission into electrical energy is called the nuclear power plant.The most important characteristic of a nuclear power plant is that a large amount of electrical energy can be produced from a relatively small amount of nuclear fuel. Therefore, the ... Read More
