摘要

Traditionally, electric power is generated on offshore platforms locally, using gas turbines. However, gas turbines have several disadvantages, including low efficiency (30 - 40 percent maximum), high carbon dioxide (CO<;sub>2<;/sub>) and nitrogen oxide (NOx) emissions, and high operating and maintenance costs. The possibility of conveying electrical power to offshore sites from more efficient and cleaner onshore generating facilities has been achieved with the invention and acceptance of voltage source converter (VSC) power transmissions as a competitive solution for long-distance shore-to-platform power delivery systems. VSC links are increasingly being deployed to connect remote renewables to consumption centers, and to enable cross-border connections, power from shore links and city-center in-feeds where space is a constraint. The compact and lightweight design of an offshore VSC converter enables it to be placed on an existing platform, changing the power source from gas turbines to onshore generation to meet existing or increased demand. It can also be fitted together with other equipment on new platforms. Power from shore improves safety for both personnel and equipment in a production and processing environment. The VSC power from shore (PFS) concept has so far been used in the following installations: Troll A 1&2 for Statoil, delivered in 2005; Valhall for BP, delivered in 2011; and Troll A 3&4 for Statoil, delivered in 2015. A 100 MW transmission to the Johan Sverdrup offshore field will be operational in 2018. The transmission to the Valhall field (78 megawatts (MW), 150 kilovolts (kV), was the first to provide general power from shore as the platform's only power source. It has been in operation for five years, and has delivered excellent performance. This paper will describe the experiences of these five years of operation and maintenance, and examine various aspects of the performance of power delivery to the platforms. In addition, it will provide some perspective regarding influences on the sending end network, and its operation.
