Hradec Substation
Hradec substation ( cs, rozvodna Hradec) is a Electrical substation#Collector substation, collector substation connecting the 220 kV and 400 kV grid in the Czech Republic's electricity grid. It is situated in Rokle near its local part Hradec in the Ústí nad Labem Region. Description In Hradec the high voltage transmission lines from the surrounding lignite-fired power stations come together and the distribution of load takes place. Hradec is starting point of two high voltage transmission lines to Germany, a 400 kV line to Chemnitz#Administrative divisions, Röhrsdorf in Saxony and a 400 kV line to GKK Etzenricht, Etzenricht in Bavaria. The transmission capacity of the line to Röhrsdorf, which went into service during 1976, is 2640 MW. The 220 kV link to Zwönitz, which was built in the 1950s, no longer exists. There are direct 400 kV interconnections from the substation to Tušimice Power Station, Tušimice and Prunéřov Power Station, Prunéřov power stations. The 400 kV l ...

Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Ústí Nad Labem Region
Ústí nad Labem Region or Ústecký Region ( cs, Ústecký kraj, , ), is an administrative unit ( cs, kraj) of the Czech Republic, located in the north-western part of the historical land of Bohemia, and named after the capital, Ústí nad Labem. It covers the majority of the former North Bohemia province ( cs, Severočeský kraj) and is part of the broader area of North Bohemia. The region borders the regions of Liberec (east), Central Bohemia (south), Plzeň (southwest), Karlovy Vary (west) and the German region of Saxony to the north. The Ústí region comprises a range of very different types of landscape. Between the high escarpment of the Ore Mountains ( cs, Krušné hory) range and the Bohemian Central Uplands with many volcanic hills, there are vast areas devastated by surface coal mining (the North Bohemian Basin), partly being recultivated into an artificial landscape with ponds, plains and groves. The Elbe river runs through the Central Uplands in a winding gorge o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a 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, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemnitz
Chemnitz (; from 1953 to 1990: Karl-Marx-Stadt , ) is the third-largest city in the German state of Saxony after Leipzig and Dresden.

GKK Etzenricht
GKK Etzenricht, an abbreviation of Gleichstromkurzkupplung Etzenricht, meaning Etzenricht HVDC-back-to-back station, was an HVDC back-to-back facility near Etzenricht in the district of Neustadt an der Waldnaab in Bavaria, Germany. It was built on the site of the Etzenricht substation, a 380 kV/220 kV/110 kV-substation, which went into service in 1970 and expanded afterwards several times. The facility was used between 1993 and 1995 for the exchange of power between Germany and the Czech Republic, operated by Bayernwerk AG (now part of TenneT). History Construction started April 26, 1991 and was completed September 1991. First power was achieved in May 1992 and a powerline to Hradec, Czech Republic was completed September 3, 1992. Trial operation started January 27, 1993 with official opening July 9, 1993. It was shut down after synchronisation of the German and the Czech Power Grid on October 18, 1995. After the synchronization of the power grids between Germany and Czech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...
