Læsø
Læsø ("Isle of Ægir, Hlér") is the largest island in the North Sea bay of Kattegat, and is located off the northeast coast of the Jutland Peninsula, the Denmark, Danish mainland. Læsø is also the name of the municipality (Danish language, Danish, ''Municipalities of Denmark, kommune'') on that island. The island is a location mentioned in several instances in Old Norse sources detailing Norse mythology. In a 2010 survey, readers of the Danish newspaper ''Kristeligt Dagblad'' voted Læsø as Denmark's second most wonderful island, behind only Fur (island). Name and Norse mythology The modern Danish language, Danish form of the island's name, ''læsø'', developed from Old Norse ''Hlésey'', meaning 'Hlér's island'.McKinnell (2005:110) and Faulkes (1995:59).

HVDC Converter Station
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line.Arrillaga, Jos; High Voltage Direct Current Transmission, second edition, Institution of Electrical Engineers, , 1998. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: * three-phase alternating current switch gear * transformers * capacitors or synchronous condensers for reactive power * filters for harmonic suppression, and * direct current switch gear. Components Converter The converter is usually installed in a building called the valve hall. Early HVDC systems used mercury-arc valves, but since the mid-1970s, solid state devices such as thyristors have been used. Converters using thyristors or mercury-arc valves are known as ''line commutated converters''. In thyristor-based converters, many thyristors are c ...

Electrical Interconnectors To And From The Synchronous Grid Of Continental Europe
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

HVDC Volgograd-Donbass
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 ...
