Abstract

The paper begins with an introduction on the reasons that lead to the use of HVDC submarine cable links. The main aspects for the choice of direct current are presented as well as the advantages deriving from the utilization of submarine cables. The second part is dedicated to a discussion on the various type of insulation that could be used in power cables and their possible application to HVDC submarine cables. In the following there is a description of the main characteristics and technical details of some particular project that at present time (1995) are in progress. Two projects are briefly presented: Spain-Morocco, a 26 km long interconnection for the transmission, in a first phase, of 700 MW from Spain to Morocco at 400 kV a.c. by means of three cables, plus one spare, of the fluid filled type. The cables are designed for a future change to d.c. 450 kV, allowing a transmission of 500 MW each (i.e., 2 GW total). One of the peculiarities of the link is the maximum water depth of 615 m (world record for submarine power cables at the time of installation). Italy-Greece, a 1km long interconnection for the transmission of 500 MW (bi-directional)more »« less

Development of 500 kV DC PPLP-insulated oil-filled submarine cable

Journal Article Fujimori, A; Tanaka, T; Takashima, H; ... - IEEE Transactions on Power Delivery

This paper outlines the development of a 500 kV DC oil-filled submarine cable capable of transmitting 2,800 MW with {+-} 500 kV 2800A bipole system. Polypropylene Laminated Paper (PPL) was employed as the insulation material, which is the worlds first application to DC cables. The conductor size is 3,000 mm{sup 2}, which is the largest size for submarine cables ever put into practical use. Through various fundamental and prototype tests, the cable proved to have excellent electrical characteristics for DC voltage as well as transient overvoltage. The cable and accessories are currently undergoing a long-term accelerated aging test as themore »« less

Development of totally metal enclosed SF/sub 6/ gas insulated HVDC converter station

Journal Article Morii, K; Matsumura, S; Harumoto, Y; ...

HVDC power transmission has increasingly acquired practical importance and a number of large-scale projects such as the 2000-MW system connecting Britain and France and the 6000-MW system in Italy and Brazil are under way. In Japan, three HVDC installations are in operation, and a stepped-up effort is directed toward the advancement of dc technology with emphasis on application to long-distance bulk power transmission and interconnection. The development of HVDC power system at voltages up to +/-500 kV is described. In the development project, the major aims were set to develop a compact and economical converter station having high reliability -more »« less
HVDC submarine cables for the Hokkaido Honshu linkage

Journal Article Minemura, S; Iso, M - Energy Dev. Jpn.; (United States)

The direct-current submarine cable interconnecting Hokkaido and Honshu (hereafter called HH linkage) is an example of installation of an undersea cable for long-distance power transmission crossing a sea strait. In particular, the feature of this interconnection is that an oil-filled (OF) cable is used for the high-voltage side with crosslinked polyethylene (XPLE) cable adopted for the return to comprise a conductor return system. The details of the facilities, especially the design of the OF submarine cable are described. 3 refs.
Performance of a technical and economic feasibility study of an HVDC compressed gas-insulated transmission line. Final report

Technical Report Dale, S

The use of compressed gas-insulated equipment in the high voltage transmission network has steadily increased over the recent years. Substations utilizing compressed gas insulation can be placed and used to bring power into urban areas at the full transmission line voltage. Compressed gas-insulated cables have found an increasingly important role in this development for feeders and interconnections to substations. The HVDC alternative has an approximate 2 : 1 advantage over an ac system for power delivery in a given corridor. Interconnection of ac systems with a HVDC link allows the ac systems to operate asynchronously and reduces the short circuitmore »« less
Energy analysis of the basic materials utilized in electric power transmission systems

Technical Report

The energy content per mile of installed underground and overhead power transmission systems has been calculated for the following types of systems: self-contained oil-filled cables; HPOF pipe-type cables; extruded dielectric cables; compressed-gas-insulated systems; overhead lines (ac and dc) and two proposed superconducting systems (ac and dc). The system operating voltages analyzed included 138, 230, 345, 500, 765 and 1,200 kV for ac systems, but all systems were not analyzed at the higher voltages. The dc overhead lines operated at +-200, +-400, +-600 and +-800 kV. Total installed energy content for these systems ranged from 4 x 10/sup 9/ to 1.2more »« less
