关于电力的英语作文

关于电力的英语作文English: Electricity is an essential part of our daily lives, powering technology, providing light, and running appliances. It is a form of energy that is generated through the movement of electrons. The generation of electricity can come from various sources such as fossil fuels, nuclear power, wind, water, and solar energy. However, the use of fossil fuels for electricity generation is a major contributor to air pollution and climate change. As a result, there is a growing movement towards renewable energy sources like wind and solar power. The transmission and distribution of electricity is done through a complex infrastructure of power lines and substations, ensuring that electricity reaches our homes and businesses efficiently. Sustainable practices and energy conservation are crucial in ensuring a reliable and clean source of electricity for future generations.中文翻译: 电力是我们日常生活中不可或缺的一部分,为技术提供动力,提供光源并运行家用电器。

Page1.The Production of Electrical Energy(电能生产)1 English texFrom reference 1See also: Wind power, Wind farm, and Wind power in the United StatesAirflows can be used to run wind turbines. Modern wind turbines range from around 600 kW to 5 MW of rated power, although turbines with rated output of 1.5–3 MW have become the most common for commercial use; the power output of a turbine is a function of the cube of the wind speed, so as wind speed increases, power output increases dramatically. Areas where winds are stronger and more constant, such as offshore and high altitude sites, are preferred locations for wind farms. Typical capacity factors are 20-40%, with values at the upper end of the range in particularly favourable sites.Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand. This could require large amounts of land to be used for wind turbines, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially more energy.Wind power is renewable and produces no greenhouse gases during operation, such as carbon dioxide and methane.Keywords:wind power,wind turinesFrom reference 2See also: Hydroelectricity and HydropowerEnergy in water can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy. There are many forms of water energy:∙Hydroelectric energy is a term usually reserved for large-scale hydroelectric dams. Examples are the Grand Coulee Dam in Washington State and theAkosombo Dam in Ghana.∙Micro hydro systems are hydroelectric power installations that typically produce up to 100 kW of power. They are often used in water rich areas as aremote-area power supply (RAPS). There are many of these installationsaround the world, including several delivering around 50 kW in the Solomon Islands.∙Damless hydro systems derive kinetic energy from rivers and oceans without using a dam.∙Ocean energy describes all the technologies to harness energy from the ocean and the sea. This includes marine current power, ocean thermal energyconversion, and tidal power.Keywords: hydropower,the Grand Coulee Dam,the Akosombo DamFrom reference 3See also: Ethanol fuel and BioEthanol for Sustainable TransportSince the 1970s, Brazil has had an ethanol fuel program which has allowed the country to become the world's second largest producer of ethanol (after the UnitedStates) and the world's largest exporter. Brazil’s ethanol fuel program uses modern equipment and cheap sugar cane as feedstock, and the residual cane-waste (bagasse) is used to process heat and power. There are no longer light vehicles in Brazil running on pure gasoline. By the end of 2008 there were 35,000 filling stations throughout Brazil with at least one ethanol pump.Nearly all the gasoline sold in the United States today is mixed with 10 percent ethanol, a mix known as E10, and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends. Ford, DaimlerChrysler, and GM are among the automobile companies that sell “flexible-fuel” cars, trucks, and minivans that can use gasoline and ethanol blends ranging from pure gasoline up to 85% ethanol (E85). By mid-2006, there were approximately six millionE85-compatible vehicles on U.S. roads. The challenge is to expand the market for biofuels beyond the farm states where they have been most popular to date. Flex-fuel vehicles are assisting in this transition because they allow drivers to choose different fuels based on price and availability. The Energy Policy Act of 2005, which calls for 7.5 billion gallons of biofuels to be used annually by 2012, will also help to expand the market.Keyword:ethanol fuel,bioethanol for sustainable transport2 中文翻译及分析出自文献1:通过对风力发电也已increasing.See:在美国风力发电,风电场,风力发电气流可用于运行风力涡轮机。

外文翻译Electric Power SystemElectric Power System, components that transform other types of energy into electrical energy and transmit this energy to a consumer. The production and transmission of electricity is relatively efficient and inexpensive, although unlike other forms of energy, electricity is not easily stored ad thus must generally be used as it is being produced.Components of an Electric Power SystemA modern electric power system consists of six main components: (1) the power station, (2)a set of transformers to raise the generated power to the high voltages used on the transmission lines, (3) the transmission lines, (4) the substations at which the power is stepped down to the voltage on the distribution lines, (5) the distribution lines, and (6) the transformers that lower the distribution voltage to the level used by the consumer’s equipment.Power Station, the power station of a power system consists of a prime mover, such as a tribune driven by water, steam, or combustion gases that operat e a system of electric motors and generators. Most of the world’s electric power is generated in steam plants driven by hydroelectric (water power), diesel, and internal-combustion plants.Transformers, Modern electric power systems use transformers to convert electricity into different voltages. With transformers, each stage of the system can be operated at an appropriate voltage. In a typical system, the generators at the power station deliver a voltage of from 1,000 to 26,000volts (v). Transformers step this voltage up to values ranging from 138,000 to 765,000 V for torture transfer on the distribution system. Another set of transformers step the voltage down again to a distribution level such as 2,400 or 4,160 V or 15, 27, or 33 kilovolts (kV). Finally the voltage is transformed once again the distribution transformed near the point of use to 240 or 120 V.Transmission Lines, The lines of high voltage transmission system areusually composed of wires of copper, aluminum-clad steel, which are suspended form tall latticework towers of steel by strings of porcelain insulators. By the use of clad steel wires and high towers, the distance between towers can be increased, and the cost of the transmission line thus reduced. In modern installations with essentially straight paths, high-voltage lines may be built with as few as six towers to the kilometer. In some areas high-voltage lines are suspended from tall wooden poles spaced more closely together.For lower voltage distribution lines, wooden poles are generally used rather than steel towers. In cites and other areas where open lines create a safety hazard or are considered unattractive, insulated underground cables are used for distribution. Some of these cables have a hollow core through which oil circulates under low pressure. The oil provides temporary protection from water damage to the enclosed wires should the cable develop a leak. Pipe-type cables in which three cables are enclosed in a pipe filled with oil under high pressure (14 kg per sq cm/200psi) are frequently used. These cables are used for transmission of current at voltage as high as 345,000V (or 345 kV).Supplementary Equipment Any electric-distribution system involves a large amount of supplementary equipment to protect the generators, transformers, and the transmission lines themselves. The system often includes devices designed to regulate the voltage or other characteristics of power delivered to consumers.To protect all elements of a power system from short circuits and overloads, and for normal switching operations, circuit breakers are employed. These breakers are large switches that are activated automatically in the event of a short circuit or other condition that produces a sudden rise of current. Because a current forms across the terminals of the circuit breaker at the moment where the current is interrupted, some large breakers (such as those used to protect a generator or a section of primary transmission line) are immersed in a liquid that is a poor conductor of electricity, such as oil, to quench the current. In large air-type circuit breakers, as well as in oil breakers, magnetic fields are used to break up the current. Small air-circuit breakers areused for protection in shops, factories, and in modern home installations. In residential electric wiring, fuses were once commonly employed for the same purpose. A fuse consists of piece of alloy with a low melting point, inserted in the circuit, which melts, breaking the circuit if current rises above a certain value. Most residences now use air-circuit breakers.Power FailuresIn most parts of the world, local or national electric utilities have joined in grid systems. The linking grids allow electricity generated in one area to be shared with others. Each utility that agrees to share gains an increased reserve capacity, use of larger, more efficient generators, and the ability to respond to local power failures by obtaining energy from a linking grid.These interconnected grids are large, complex systems that contain elements operated by different groups. These systems offer the opportunity for economic saving and improve overall reliability but can create a risk of widespread failure. For example, the worst blackout in the history of the United States and Canada occurred august 14, 2003, when 61,800 megawatts of electrical power was lost in an area covering 50 million people. (One megawatts of electricity is roughly the amount needed to power 750 residential homes.) The blackout prompted calls to replace aging equipment and raised questions about the reliability of the national power grid.Despite the potential for rare widespread problems, the interconnected grid system provides necessary backup and alternate paths for power flow, resulting in much higher overall reliability than is possible with isolated systems. National or regional grids can also cope with unexpected outages such as those caused by storms, earthquakes, landslides, and forest fires, or due to human error or deliberate acts of sabotage.Power qualityIn recent years electricity has been used to power more sophisticated and technically complex manufacturing processes, computers and computer network, and a variety of other high-technology consumer goods. These products and processes are sensitive not only to the continuity of power supplybut also to the constancy of electrical frequency and voltage. Consequently, utilities are taking new measure to provide the necessary reliability and quality of electrical power, such as by providing additional electrical equipment assure that the voltage and other characteristics of electrical power are constant.Voltage Regulation long transmission lines have considerable inductance and capacitance. When current flows through the lines, inductance and capacitance have the effect of varying the voltage on the line as the current varies. Thus the supply voltage varies with the load. Several kinds of devices are used to overcome this undesirable variation in an operation called regulation of the voltage. The devices include induction regulation and three-phase synchronous motors (called synchronous condensers), both of which vary the effective amount of inductance and capacitance in the transmission circuit.Inductance and capacitance react with a tendency to nullify one another. When a load circuit has more inductive than capacitive reactance, as almost invariably occurs in large power systems, the amount of power delivered for a given voltage and current is less than when the two are equal. The ratio of these two amounts of power is called the power factor. Because transmission-line losses are proportional to current, capacitance is added to the circuit when possible, thus bringing the power factor as nearly as possible to 1. For this reason, large capacitors are frequently inserted as a part of power-transmission systems.World Electric Power Production Over the period from 1950 to 2003, the most recent year for which data are available, annual world electrical power production and consumption rose from slightly less than 1 trillion kilowatt-hours (kw h ∙) to 15.9 trillion kw h ∙ A change also took place in the type of power generation. In 1950 about two-thirds of the world’s electricity came from steam-generating sources and about one-third from hydro electric sources. In 2003thermal sources produced 65 percent of the power, but hydropower had declined to 17 percent, and nuclear power accounted for 16percent of the total. The grown in nuclear power showed in some countries, notably the United States, in response to concerns about safety. Nuclear plants generated 20 percent of U.S. electricity in 2003; in France, the world leader, the figure was 78 percent.ConservationMuch of the world’s electricity is produced from the use of nonrenewable resources, such as natural gas, coal, oil, and uranium. Coal, oil, and natural gas contain carbon, and burning these fossil fuels contributes to global emissions of carbon dioxide and other pollutants. Scientists believe that carbon dioxide is the principal gas respon sible for global warming, a steady rise in Earth’s surface temperature.Consumers of electricity can save money and help protect the environment by eliminating unnecessary use of electricity, such as turning off lights when leaving a room. Other conservation methods include buying and using energy-efficient appliances and light bulbs, and using appliances such as washing machines and dryers, at off-peak production hours when rates are lower. Consumers may also consider environmental measures such as purchas ing “green power” when it is offered by a local utility, “Green power” is usually more expensive but relies on renewable and environmentally friendly energy sources, such as wind turbines and geothermal power plants.电力系统介绍电力系统把其它形式的能源转化为电能并输送给用户。
