BARD Offshore 1
BARD Offshore 1 is a 400 megawatt (MW) North Sea offshore wind farm with 80 BARD 5.0 turbines. Since the owner could not buy such 5MW offshore wind turbines in sufficient numbers in 2006, Dr. Bekker set up its own production of turbines. This should serve as the legacy for his children. The systems were developed by aerodyn Energiesysteme GmbH. A plant for rotor blades and nacelle assembly was built in Emden and a plant for the offshore foundations in Cuxhaven. Two turbine prototypes were set up at the Rysumer Nacken in 2007, and another prototype in Hooksiel in 2008. Construction was finished in July 2013 and the wind farm was officially inaugurated in August 2013. The wind farm is located northwest of the isle Borkum in deep water. Laying of cables to connect the wind farm started on 23 July 2009. The 200 km connection is the longest of its kind in the world. It is also the first connection of an offshore wind park realized as HVDC-transmission. Construction of the win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonics (electrical Power)
In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency. Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines. They are a frequent cause of power quality problems and can result in increased equipment and conductor heating, misfiring in variable speed drives, and torque pulsations in motors and generators. Harmonics are usually classified by two different criteria: the type of signal (voltage or current), and the order of the harmonic (even, odd, triplen, or non-triplen odd); in a three-phase system, they can be further classified according to their phase sequence (positive, negative, zero). Current harmonics In a normal alternating current power system, the current varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear time-invariant electrical load is connected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Farms In Germany
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various asp ...

Borkum Riffgat
Riffgat (also known as Borkum Riffgat and OWP Riffgat) is an offshore wind farm to the north-west of the German island of Borkum and north of the eponymous shipping channel in the southern North Sea. The wind turbines are built across an area of . It consists of 30 turbines with a total capacity of 108 megawatt (MW), and is expected to generate enough electricity for 112,000 households. Early 2011, the Dutch government stated that the wind farm was partly in Dutch territory and protested against the issuing of construction licenses by the German government. The issue was resolved in 2014 with the signing of the Ems-Dollart-Treaty. Between November 2015 and April 2016, transmission problems prevented Riffgat from exporting power.

Feed-in Tariffs In Germany
Feed-in electricity tariffs (FiT) were introduced in Germany to encourage the use of new energy technologies such as wind power, biomass, hydropower, geothermal power and solar photovoltaics. Feed-in tariffs are a policy mechanism designed to accelerate investment in renewable energy technologies by providing them remuneration (a "tariff") above the retail or wholesale rates of electricity. The mechanism provides long-term security to renewable energy producers, typically based on the cost of generation of each technology. Technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting higher costs. As of July 2014, feed-in tariffs range from 3.33 ¢/kWh (4.4 ¢/kWh) for hydropower facilities over 50 MW to 12.88 ¢/kWh (17.3 ¢/kWh) for solar installations on buildings up to 30kWp and 19 ¢/kWh (25.5 ¢/kWh) for offshore wind.

Availability Factor
The availability factor of a power plant is the amount of time that it is able to produce electricity over a certain period, divided by the amount of the time in the period. Occasions where only partial capacity is available may or may not be deducted. Where they are deducted, the metric is titled ''equivalent availability factor'' (EAF). The availability factor should not be confused with the capacity factor. The capacity factor for a given period can never exceed the availability factor for the same period. The difference arises when the plant is run at less than full capacity, in which case the capacity factor is less than the availability factor. The availability of a power plant varies greatly depending on the type of fuel, the design of the plant and how the plant is operated. Everything else being equal, plants that are run less frequently have higher availability factors because they require less maintenance and because more inspections and maintenance can be scheduled duri ...

BorWin Alpha
HVDC BorWin1 is the first HVDC facility in the world to be built for importing power from an offshore wind park to shore, and the first to use voltage source converters (VSC) in Germany. It connects the offshore wind park BARD Offshore 1 and other offshore wind farms in Germany near Borkum to the European power grid. The facility was built by ABB and has a capacity of 400 MW at a bipolar voltage of ±150 kV. HVDC BorWin1, which leads from BorWin Alpha Offshore Platform to Diele substation, consists of a of underground and of submarine cable. Unlike the later (and more powerful) HVDC connections that have been built for transmitting wind power to shore in Germany, Borwin 1 uses cascaded two-level converter submodules, i.e., a modular multilevel converter (MMC) scheme with a large step size, in which each half-bridge submodule contains several IGBTs connected in series for the required submodule voltage rating. Pulse-width modulation (PWM) is used to impro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overvoltage
When the voltage in a circuit or part of it is raised above its upper design limit, this is known as overvoltage. The conditions may be hazardous. Depending on its duration, the overvoltage event can be transient—a voltage spike—or permanent, leading to a power surge. Explanation Electronic and electrical devices are designed to operate at a certain maximum supply voltage, and considerable damage can be caused by voltage that is higher than that for which the devices are rated. For example, an electric light bulb has a wire in it that at the given rated voltage will carry a current just large enough for the wire to get very hot (giving off light and heat), but not hot enough for it to melt. The amount of current in a circuit depends on the voltage supplied: if the voltage is too high, then the wire may melt and the light bulb would have "burned out real time". Similarly other electrical devices may stop working, or may even burst into flames if an overvoltage is de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
