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 ...

High-voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) 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. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC 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 ...

Kristiansand
Kristiansand is a seaside resort city and municipality in Agder county, Norway. The city is the fifth-largest and the municipality the sixth-largest in Norway, with a population of around 112,000 as of January 2020, following the incorporation of the municipalities of Søgne and Songdalen into the greater Kristiansand municipality. In addition to the city itself, Statistics Norway counts four other densely populated areas in the municipality: Skålevik in Flekkerøy with a population of 3,526 in the Vågsbygd borough, Strai with a population of 1,636 in the Grim borough, Justvik with a population of 1,803 in the Lund borough, and Tveit with a population of 1,396 () in the Oddernes borough. Kristiansand is divided into five boroughs: Grim, which is located northwest in Kristiansand with a population of 15,000; Kvadraturen, which is the centre and downtown Kristiansand with a population of 5,200; Lund, the second largest borough; Søgne, with a population of around 12,000 and i ...

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 large distances. There are a number of international power cables from Norway to abroad, including lines to Sweden (3,600  MW), Finland (120 ...

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 Great B ...

Thyristor
A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). 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). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more complex devices that incorporate at least four layers of alternating N-type and P-type substrate. The first thyristor devices were ...
