Electrical Energy, Transmission, And Distribution

CHAPTER 1 INTRODUCTION PROBLEM SUMMARY AND INTRODUCTION The energy can neither be created nor be destroyed but it can be converted from one form to another. Electrical energy is widely used in day to day life in various applications. The generation of as electrical energy is nothing but the conversion of various other forms of energy into electrical energy. This generated energy is demanded by the consumers. There are three main parts of power system network: Generation, Transmission and Distribution. Fig. 1.1 Generation, Transmission and Distribution Energy consumption is calculated mainly in kW. Watts, kilowatts, megawatts are the units for electricity. The smallest unit is watts; if you consider 1000 W then it is 1 kW. 1000 kW = 1 MW. Also, Consumption is a measure of how much energy you have purchased from your electricity utility. The SI unit of energy is the joule, but this is a very small quantity, so electricity utilities use kilowatt hours (kWh) instead of joules. The rate at which you use energy is called power, and is measured in watts (W). But you are not charged for the rate at which you use energy, only the amount of energy used. The power of the generating station, and is normally measured in megawatts (MW).Today accuracy in electrical billing is highly recommended. The calculation of energy consumption gives real power consumption as well as accurate billing. It provides real time monitoring of electricity uses. It is less time consuming and cost effective.Show MoreRelatedElectricity: Electrical Grids1155 Words   |  5 PagesFor over more than a century, coal and other fossil fuels has been used by the power plants as the most favoured resource for power generation. This process is carried out with the help of the grids. Presently, more than 70% of the total global energy demand is satisfied by the burning of fossil fuels. If we continue to utilize fossil fuels to meet the needs of present generation, soon they will get exhausted and our future generation would be deprived of it. The consumptionRead MoreWireless Electricity721 Words   |  3 PagesWireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. The tangle of cables and plugs needed to recharge todays electronic gadgets could soon be a thing of the past. The concept exploits century-old physics and could work over distances of many metres. Consumers desire a simple universal solution that frees them from the hassles of plug-in chargers and adaptors.Wireless power technologyRead MoreElectrical Power Distribution By Shaun Bannon981 Words   |  4 PagesElectrical Power Distribution By Shaun Bannon Content 1.1 Introduction 1.2 Overview 1.3 Hydro Power Stations 1.4 Thermal Power Stations 1.5 Nuclear Power Stations 1.6 Diesel Power Stations 1.7 Bibliography 1.1 Introduction A power station consists of several generating stations and transmissions and distribution networks interconnect consumers. The purpose of any power system is to generate electrical energy in sufficient quantities at the best-suited locations, to transmit it to various loadRead MoreElectrical Device Between Two Circuit Through Electromagnetic Induction1205 Words   |  5 PagesINTRODUCTION The transformer is an electrical device which transfers energy between two circuit through electromagnetic induction. Transformer may be used as a safe and efficient voltage changer to change the Alternating Current voltage at it’s input to a higher and lower voltage at its output without changing it’s frequency. Other uses include current conversion, isolation with or without changing impedance and voltage conversion. A transformer consists of two windings of wire that are wound aroundRead MoreElectrical Energy Supply by Different Energy Sources Essay852 Words   |  4 PagesFor electricity to be generated there is a need for a source of energy. Some of these sources will include Wind, liquid water forced to move at high velocity or steam projected at high pressure. The energy harnessed from these sources is used to run large turbine devices which in turn run attached generators that produce electricity that is the extracted and distributed. These sources produce mechanical and kinetic energy that is extracted by massive turbine devices that have blades spinning at greatRead MoreThe Global Consumption Of Energy1264 Words   |  6 PagesIntroduction The 21st century can be named as the energy century because the global consumption of energy is ever expanding and our ever increasing consumption of energy has led to serious environmental problems. For instance Global warming is majorly attributed to our high energy intake. So, if we continue with this irresponsible pattern of energy consumption, our future will no longer be sustainable. Hence, managing and optimizing all the available resources has become a necessity when all theRead MoreAn Investigation Into The Social And Economic Drawbacks Of A International Super Grid1589 Words   |  7 Pagesstartling figure. In this dissertation I will be analysing how the efficiency in the generation and transmission of electricity could be improved across the UK. Along with a consideration of the possible future fuels that could be used to satisfy our electricity demand. With this huge demand of electricity within the UK it s hardly surprising that the UK between 2007 and 2012, has had a peak electrical demand 52.5 GW. To put that in perspective that s 52500000000W! Within The EU !!!!!!!!!!!! accessRead MoreSmart Grid Technologies : Introduction1465 Words   |  6 PagesSMART GRID TECHNOLOGIES: INTRODUCTION: All the service connections, transformers, transmission infrastructure, substations, generation plants, and everything required in managing the generation and distribution of electrical power is known as the electrical â€Å"Grid.† The term â€Å"smart grid† has been used to describe a broad range of technologies, design concepts and operating practices that collectively paint an exciting picture of what our electric power infrastructure might look like in ten or twentyRead MoreApplications Of Distribution Generation Storage Distribution System1376 Words   |  6 Pages APPLICATIONS OF DISTRIBUTION GENERATION STORAGE DISTRIBUTION SYSTEM.
