Type testing of the GTO valves for a novel STATCOM convertor
A relocatable static VAr compensator (SVC), rated 0 to +225 MVAr at 400 kV, has been supplied to the National Grid Company (NGC) for its East Claydon substation in Buckinghamshire, England. The SVC comprises a fixed filter of 23 MVAr, a con...
HVDC East-South interconnector II in India: 2000 MW, +/-500 kV
In India there are presently six HVDC systems in operation which have contributed considerably to the linking of its dissimilar regional grids. In March 2000, Powergrid, the largest power transmission utility of India, awarded a new long di...
An example in sizing a series compensation scheme with fixed and variable capacitors
FACTS technology is slowly finding its way in the electric power industry. Although many FACTS controllers have been defined, some might never materialize, others are finding their place, and new ones will surely appear for specific, applic...
Innovative technology in the Moyle Interconnector
Power-transmission by high voltage direct current (HVDC) technology has been in commercial use for more than 40 years. Even though the basic concept has remained unchanged during the past decades, many technological improvements have been d...
Capacitor commutated converters for high power HVDC transmission
Two concepts for the transmission with a high power capacity using HVDC technology are analysed in this paper. The technology of capacitor commutated converters (CCC) is presented and the design of two system models is described. Their stea...
Modular back-to-back HVDC, with capacitor commutated converters (CCC)
A back-to-back HVDC arrangement is used when two asynchronous AC systems need to be interconnected for bulk power transmission or for AC system stabilization reasons. In an HVDC back-to-back station there are no overhead lines or cables sep...
A comparison of conventional and capacitor commutated converters based on steady-state and dynamic considerations
The capacitor commutated HVDC converter (CCC) is evaluated using steady-state as well as transient analysis. The steady-state analysis indicates that the CCC device is superior to the conventional converter when operating into very weak AC-...
Recent advances in space charge measurement and extruded HVDC cable design
The design of high power HVDC cables is a challenge. The field and space charge distributions over the insulation thickness, which somehow control the cable behaviour and its life expectancy have never been measured up to now and the cable....
Gas-insulated line (GIL) of the 2/sup nd/ generation
With the commissioning of the 500 m long gasinsulated transmission line (GIL) at the Geneva Airport, Siemens is the first manufacturer of the second generation GIL world-wide. This project concluded successfully the recent development works...
Cost-efficient XLPE cable system solutions
In this paper, different XLPE transmission system solutions are described in terms of technology, ecology and economy. Based on the growing experience of XLPE cable systems and their qualitative improvements during the years, a condensed re...
