Power electronics in HVDC power transmission

Power Engineering Journal, 1994
This article describes the function and the hardware of a typical scheme for high-voltage direct current power transmission. Its basis is a 2×500 MW back-to-back scheme to interconnect the Western and Southern power regions of India. This technology permits sophisticated and rapid control of power system quantities-power, reactive power, frequency and ...

Powerful platform [offshore HVDC transmission]

Power Engineer, 2006
Bringing power to one of the world's largest oil and gas platforms was not easy, but Troll A in the North Sea is now reaping the benefits. In February 2005, the world's first offshore HVDC transmission was successfully commissioned. Consisting of two parallel 40 MW transmissions connecting the Troll A gas platform in the North Sea, with the mainland ...

Transient analysis of HVDC power transmission systems

European Transactions on Electrical Power, 2004
AbstractThis paper describes a method for dynamic simulation of HVDC transmission systems based on transient circuit analysis during abnormal conditions. Such conditions include sudden drop or rise in the AC system voltage at the rectifier or inverter sides and short‐circuit faults on the DC link. The waveforms of the calculated DC current and terminal

HVDC transmission technology for sustainable power supply

International Multi-Conference on Systems, Sygnals & Devices, 2012
The necessity to limit CO 2 emissions as well as the renunciation of nuclear power in many countries are the chief factors that determine the future development of electric power generation. These requirements can be met by integrating renewable energy sources, such as offshore wind farms and solar power from North Africa.

Adaptive Control for HVdc Power Transmission Systems

IEEE Transactions on Power Apparatus and Systems, 1985
The transient performance of High Voltage Direct Current (HVdc) power transmission systems depends heavily on the current regulators associated to the converter control systems. The tuning of these current regulators is a function of the converters short-circuit ratio, or equivalently of all the net converter commutation resistances.

Hybrid HVDC system for power transmission to island networks

2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004
A hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for the connection of networks with no synchronous generation to a main grid. The proposed system combines the robust performance and low capital cost and power loss of a line-commutated HVDC converter, with the fast dynamic performance of a ...

Power Transmission with HVDC at Voltages Above 600 kV

2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005
The use of ultra high voltage direct current (UHVDC), i.e. voltages above the highest in use, 600 kV, has been found to be economically attractive for power blocks up to 6000 MW for distances above 1000 km, Furthermore the use of 800 kV as transmission voltage will be achievable within the near future with a limited amount of development work none of ...
