Cross-Skagerrak
Skagerrak is the name of a 1,700 MW high-voltage direct current (HVDC) transmission facility between Tjele (Denmark) and Kristiansand (Norway). It is owned and operated by Statnett in Norway, and Energinet in Denmark. The lines connect the hydroelectric-based Norwegian grid and the wind and thermal power-based Danish grid. In operation it enables more renewable energy in the energy mix, and more efficient use of electricity. Technical features The Skagerrak 1–3 scheme consists of a overhead line and a underwater cable. It has a capacity of 1,050 megawatts (MW). Both land parts in Denmark and in Norway uses overhead lines from the cable landing point to the converter stations. The overhead lines in Denmark are set to be renovated in 2016 for increased lifespan. The towers were originally constructed for four poles, but were rebuilt for three conductors (three poles) when Skagerrak 3 was established. Near Aggersund HVDC Skagerrak crossed Aggersund strait overhead on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. HVDC lines are commonly used for long-distance power transmission, since they require fewer conductors and incur less power loss than equivalent AC lines. HVDC also allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as 50 and 60 Hz. This improves the stability and economy of each grid, by allowing the exchange of power between previously incompatible networks. The modern form o ...

Statnett
Statnett is a Norwegian state-owned enterprise responsible for owning, operating and constructing the stem power grid in Norway. The company has its headquarters in Oslo, Norway. Statnett also owns 30% of the Nord Pool Spot along with other Nordic transmission system operators. Network Statnett is the transmission system operator in Norway, operating of high power lines. There are plans to upgrade the western grid from 300 to 420 kV at a cost of 8 billion NOK, partly to accommodate cables to Germany and England. The power grid in Norway is divided into three sectors: the stem net, the regional net and the local net. While it is often local municipalities who own the regional and local net, the government through Statnett owns the stem net. The stem net typically has 300 to 420 kilovolts (kV) and is used to transport electricity across long distances. There are a number of international power cables from Norway to abroad, including lines to Sweden (3,600 MW), F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energinet
Energinet is the Danish national transmission system operator for electricity and natural gas. It is an independent public enterprise owned by the Danish state under the Ministry of Climate and Energy. Energinet has some 1150 employees, and its headquarters are located in Erritsø near Fredericia in Jutland. The gas division is located in Ballerup near Copenhagen. The main tasks are to ensure efficient operation and development of the national electricity and gas infrastructure as well as ensuring equal access for all users of the infrastructure. History Energinet was created by a merger of power grid operators Eltra, Elkraft System and Elkraft Transmission, and by natural gas transmission system operator Gastra. The merger took place on 24 August 2005 with retrospective effect from 1 January 2005. Eltra owned the electricity transmission network west of the Great Belt and was system operator there. It was owned by 44 network companies there. To the east of the Grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thyristor
A thyristor (, from a combination of Greek language ''θύρα'', meaning "door" or "valve", and ''transistor'' ) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications like inverters and radar generators. It usually consists of four layers of alternating P- and N-type materials. It acts as a bistable switch (or a latch). There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its gate lead controls the larger current of the anode-to-cathode path. In a two-lead thyristor, conduction begins when the potential difference between the anode and cathode themselves is sufficiently large (breakdown voltage). The thyristor continues conducting until the voltage across the device is reverse-biased or the voltage is removed (b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
