Rivera HVDC Back-to-back Station
Rivera HVDC Back-to-back station is the first HVDC Back-to-back station situated south of Rivera, Uruguay Rivera () is the capital of Rivera Department of Uruguay. The border with Brazil joins it with the Brazilian city of Santana do Livramento, which is only a street away from it, at the north end of Route 5. Together, they form an urban area of aro ... at . It was built by Areva and inaugurated in 2000. Rivera HVDC Back-to-back station whose function is to perform a conversion of 50 Hz power from the power grid of Uruguay into 60 Hz for the power grid of Brazil, operates with a DC voltage of 20 kV. The transmission rate is 70 MW. Rivera HVDC Back-to-back station is connected with the power grid of Uruguay by a short single-circuit 150 kV line to Rivera substation situated at . The connection to the power grid of Brazil is done by a single-circuit 230 kV AC line, which crosses the border between Uruguay and Brazil at and ends at Livramento Substation {{coord, 30, 51, 44, S, 55, 3 ...

Rivera, Uruguay
Rivera () is the capital of Rivera Department of Uruguay. The border with Brazil joins it with the Brazilian city of Santana do Livramento, which is only a street away from it, at the north end of Route 5. Together, they form an urban area of around 200,000 inhabitants. As of the census of 2011, it is the sixth most populated city of Uruguay. History On 21 March 1860 a ''pueblo'' (village) named Pereira was created by the Act of Ley Nº 614. On 7 May 1862, it was substituted by the ''villa'' (town) named Ceballos and founded by the Act of Ley Nº 704, in honour of the Spanish viceroy Pedro de Cevallos. In July 1867 it took on the official name Rivera and was recognized as a ''villa''. The Brazilian town Santana do Livramento already existed just across the border. On 1 October 1884, it became capital of the Department of Rivera by the Act of Ley Nº 1.757. Its status was elevated to ''ciudad'' (city) on 10 June 1912 by the Act of Ley Nº 4.006. In 1943, the Plaza Internacion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melo HVDC Back-to-back Station
The Melo HVDC Back-to-back station is the central part of the EHV-interconnection between Uruguay and Brazil, which is only possible by means of a frequency converter, as the frequency of the power grid in Uruguay is 50 Hz and that in Brazil is 60 Hz. The station, which is situated east of Melo, Uruguay, is interconnected by the San Carlos substation with a 283 kilometres long 500 kV line. It is capable of transferring 500 MW, and was built by AREVA in 31 months from 2009 to 2011. From the Melo station a 128 kilometres long 525 kV powerline, of which 65 km are situated in Uruguay, runs to a newly built 525 kV/230 kV substation close to the Candiota power station, which contains some harmonic filters.

Back-to-back Connection
A back-to-back connection is the direct connection of the output of one device to the input of a similar or related device. Telecommunications In telecommunications, a back-to-back connection can be formed by connecting a transmitter directly to a receiver without a transmission line in between.Federal Standard 1037C and from MIL-STD-188 This is used for equipment measurements and testing purposes. The back-to-back connection eliminates the effects of the transmission medium. In some cases, the output of a receiving device is instead connected to the input of a transmitting device. Power transmission A back-to-back connection for electric power transmission is a high-voltage direct-current (HVDC) system with both ends in the same switchyard. This is used to couple asynchronously operated power grids or for connecting power grids of different frequencies where no DC transmission line is necessary. Electronics In electronics, a back-to-back connection is the connection of tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Power Infrastructure In Uruguay
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...
