Hradec Substation
Hradec substation () 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 line to Etzenricht is ...

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 the 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. There are 55,000 substations in the United States. Substations are also occasionally known in some countries as switchyards. 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 distri ...

Lignite
Lignite (derived from Latin ''lignum'' meaning 'wood'), 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. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is 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 and left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brownish-bl ... [...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 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] |
