Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerfu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PV System
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct current, direct to alternating current, as well as photovoltaic mounting system, mounting, solar cable, cabling, and other electrical accessories to set up a working system. Many utility-scale PV systems use Solar tracker, tracking systems that follow the sun's daily path across the sky to generate more electricity than fixed-mounted systems. Photovoltaic systems convert light directly into electricity and are not to be confused with other solar technologies, such as concentrated solar power or Solar thermal energy, solar thermal, used for heating and cooling. A solar array only encompasses the solar panels, the visible part of the PV system, and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Energy Storage Projects
This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual energy storage plants augment electrical grids by capturing excess electrical energy during periods of low demand and storing it in other forms until needed on an electrical grid. The energy is later converted back to its electrical form and returned to the grid as needed. Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in List of pumped-storage hydroelectric power stations. This article list plants using all other forms of energy storage. Another energy storage method is the consumption of surplus or low-cost energy (typically during night time) for conversion into resources such as hot water, cool water or ice, which is then used for heating or cooling at other times when electricity is in higher demand and at greater cost per kilowatt hour (kWh). Such thermal energy storage is often employed at end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For electric utility, utilities in the electric power industry, it is the stage prior to its Electricity delivery, delivery (Electric power transmission, transmission, Electric power distribution, distribution, etc.) to end users or its Grid energy storage, storage, using for example, the Pumped-storage hydroelectricity, pumped-storage method. Consumable electricity is not freely available in nature, so it must be "produced", transforming other forms of energy to electricity. Production is carried out in power stations, also called "power plants". Electricity is most often generated at a power plant by electromechanical electric generator, generators, primarily driven by heat engines fueled by combustion or nuclear fission, but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Declared Net Capacity
{{no footnotes, date=October 2014 Declared net capacity (DNC) is a measure of the contribution that a power station makes to the overall capacity of a distribution grid. It is measured in megawatts (MW), or in ''megawatts electrical'' (MWe) for a thermal power station. DNC is sometimes expanded as ''developed net capacity'' in British English; The two expansions have exactly the same meaning. In a conventional power station, the DNC rating is simply the maximum rated output minus the power consumed onsite. It is sometimes termed the ''switchyard'' output, and takes no account of transmission losses in the grid, which may be considerable in the case of a remote hydro station for example. Most but not all quoted power station ratings are DNC ratings rather than the simple capacity of the alternators. In the case of a wind power station, the situation is more complex. The alternator of a wind turbine is normally specified to match the strongest wind in which the turbine is designed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Availability Factor
The availability factor of a power plant is the duration it achieves production of electricity divided by the duration that it was planned to produce electricity. In the field of reliability engineering, ''availability factor'' is known as operational availability, A_o. The capacity factor of a plant includes numerous other factors which determine the durations the plant is planned to produce electricity. A solar photovoltaic plant is not planned to operate in the dark of a night, hence unplanned maintenance occurring whilst the sun is set does not impact the availability factor. Periods of generation where only partial generation of planned capacity occurs may or may not be deducted from the availability factor. An example of partial generation is a power plant with four installed turbines planned to be concurrently operational, but one of those turbines subsequently requires unplanned maintenance. Where deductions are made the metric is titled ''equivalent availability factor' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Grid
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the ''power grid''. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same ...

Electrical Generator
In electricity generation, a generator, also called an ''electric generator'', ''electrical generator'', and ''electromagnetic generator'' is an electromechanical device that converts mechanical energy to electrical energy for use in an external circuit. In most generators which are rotating machines, a source of kinetic power rotates the generator's shaft, and the generator produces an electric current at its output terminals which flows through an external circuit, powering electrical loads. Sources of mechanical energy used to drive generators include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. Generators produce nearly all of the electric power for worldwide electric power grids. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rating Plate
A rating plate on a machine carries information about its operational limits. The plate frequently contains the names of the machine and its manufacturer, so the rating plate is often called a name plate (hence the term "nameplate capacity" for a generator), although many devices carry separate nameplates and rating plates. For an electric machine, the power rating is the number on its rating plate and corresponds to a maximum electric load it can carry. There is a distinction between the ''continuous rating'' (for generators, continuous maximum rating or CMR), at which the machine can be operational without a time limit and short-term rating that can only be used for a specified amount of time. Generators A typical electrical generator rating plate contains the following parameters: * ''power rating'' is specified in terms of apparent power (KVA or MVA), since the exact power factor will be determined by the external factors; * ''power factor'' (PF) is the nominal power factor ...
