Embodiment Construction

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the description with redundant detail.

[0021] Referring first to Figure 1, there is shown a power transmission system 100 arranged in accordance with some embodiments of the present invention to implement its principles. The power transmission system 100 is installed to provide power to a subsea system 130, such as a modular subsea processing system. Power is supplied to the subsea system 130 from the offshore platform over a distance greater than 100 kilometers. The power transmission system 100 includes a master station 110 , a remote power conversion facility 120 and an integrated supply umbilical (Integrated Services Umbilical, or ISU) 150 . The master station 110 transmits DC pow...

Abstract

The present invention relates to an electrical power transmission system (100) which utilizes HVDC technology to supply power over long distance to an underwater system (130) such as a modular seabed processing system (300). The system (100) comprises a host station (110), a remote power conversion facility (120) and an Integrated Service Umbilical (150) which is connected to the underwater system (130). The host station (110) transmits DC power through a submarine power cable (140) to the remote power conversion facility (120) which is more than 100 km from the host station (110). Thereon, the remote power conversion facility (120) which includes a DC to AC inverter (123), a transformer (122) and a local control station (121), converts the DC power to the required AC power for the underwater system (130). The operation of the transmission of power to the underwater system (130) is monitored and controlled through a master local control station (111) at the host station (110) and/or a local control station (121) on the remote power conversion facility (120). Advantageously, electrical power may be supplied to an underwater system (130) which is more than 100 km from a power source. In addition, the underwater system (130) and the power transmitted can be remotely monitored and controlled.

Description

technical field [0001] The present invention relates to a power transmission system, and more particularly to a power transmission system utilizing high voltage direct current (HVDC) technology to transmit power to subsea systems and installations, such as modular subsea processing systems. Background technique [0002] High Voltage Direct Current (HVDC) is a power transmission technology in which power is converted from alternating current (AC) to direct current (DC) at the transmission end and back to alternating current at the receiving end. High voltage direct current technology is a solution to the transmission of alternating current power over long distances (greater than 100 kilometers) where direct transmission of alternating current is not feasible due to excessive power loss. In addition, HVDC technology allows power transfer between unsynchronized AC distribution systems. Thus, HVDC increases system stability by preventing cascading failures from propagating as t...
