Electric power

Electric power transmission "Electric transmission" redirects here. For vehicle transmissions, see diesel-electric transmission. [pic] [pic] 400 kV high-tension transmission lines near Madrid Electric power transmission or "high-voltage electric transmission" is the bulk transfer of electrical energy, from generating power plants to substations located near population centers. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred

The existing electric power grids face new challenges with the growing economies that are dependent on electricity. These challenges put the ability of the current electric power grids at risks of being able to deliver efficient, reliable and clean power energy to meet the demand of the growing economies. The reliability of the existing electric power girds during peak load conditions is ensured mainly by having excessive power capacity in the whole system [1]. Excessive power capacity necessitates

Research Background Power electronics circuits convert electric power from one form to other using electronic devices. By using semiconductor devices as switches power electronics circuits function, thereby controlling or modifying a voltage or current. Power electronics application range from high-power conversion equipment such as dc power transmission to everyday appliances, such as cell phone chargers, cordless screwdrivers, power supplies for computers, and hybrid automobiles. Power electronics includes

Electric Utilities are a vital industry to the overall economy, and to our very way of life. Keeping the lights on, is for many people, the reason they go to work, that along with food, and other necessities. Therefore these companies serve a very important role, and just like other industries there is competition. Specifically, for our purposes, the electric utilities industry I’m going to focus on is the transmission of power from a generator, to a distribution center, another utilities company

increasing rapidly. To mitigate this pollution, the concept of electric vehicle arose. The electric vehicles contribute in reducing the carbon dioxide emissions[1]. Thus, the use of electric vehicles is getting more popular as time goes by. As a result of that, electric vehicles must be integrated to the electric grid. They will be treated as electric loads, which means that all concepts of power system will be applied on them. Therefore, when electric vehicles are charged, they will cause voltage drop on

Electric power converters For various purposes electric power or electric energy is converted from one form to another, such as converting from AC to DC, or vice versa or just changing the voltage or frequency level. According to the input and output are alternating current (AC) or direct current (DC), power conversion can be classify as: AC to DC Rectifier Mains power supply unit (PSU) Switched mode power supply DC to AC Inverter DC to DC DC-to-DC converter Voltage stabilizer Linear regulator

ABSTRACT This paper examined solving electric power transmission line faults using hybrid artificial neural

Automakers prefer to produce gas power cars instead of electric cars. They say that gas powered cars does not have a hug effect on the environment pollution. Although I understand this point of view, I have a different opinion. I believe that all cars should be converted to electric one by the year of 2017 because electric cars will reduce the amount of greenhouse gasses that harm the earth, and it will help in reducing the amount of noise pollution. First, electric cars help reduce the amount of

Tesla Motors is a technology company, which manufactures and promotes in-house designs for technological components. Tesla Motors is an electric power train and car manufacturer, founded with the goal of providing an emission-less, cheaper and more reliable automotive vehicle rather than such with an IC engine. The auto manufacturing market is very competitive, especially for alternative fuel vehicles that has become more popular with the rise of environmental concerns. Company has a limited amount

With the invention of the first electric car in 1837 by chemist Robert Davidson of Aberdeen, there was the hope for cleaner transport system. The electric vehicle used power from galvanic cells or batteries. He later in 1841 advanced to a seven-ton vehicle that used two direct reluctant motors. The two motors had more energy than galvanic cells. The electric vehicle would move at a speed of four miles per hour. Electric vehicles were very common in 18th and 19th century. Most people found them convenient
