Lillgrund bei Malmoe, Schweden. 7. August 2008The Lillgrund wind farm is located in the Øresund between Malmö and Copenhagen. For this projectSiemens installed 48 2.3-93 wind turbines each rated at 2.3 megawatts (MW). The wind farm with a totalinstalled capacity of 110 MW is operated by the Swedish utility Vattenfall and officially went on line in June2008. It produces enough electricity to supply 60,000 Swedish households. The offshore substation platform(in the foreground) bundles the generated power and a 120-MVA power transformers transforms the 33kilovolts to a transmission voltage of 138 kilovolts so that the power generated by the wind farm can be fedinto the Swedish grid. Beside the transformer the platform also accommodated medium-voltage switchgearand an auxiliary power transformer for the substation.

Norway’s Kongsberg Maritime plans to develop a new instrumentation system to cut the cost of offshore wind operation by applying cross-sector technology and expertise to boost turbine uptime.

The company’s NKr22m ($3.8m) Windsense project – a joint effort with instrumentation specialist NCEI (Norwegian Centres of Expertise Instrumentation) – aims to adapt equipment and maintenance methods common in the maritime and offshore oil and gas industries to cut unplanned shutdowns at wind farms.

As well as improving reliability via remote control and monitoring, the system gives operators the option to temporarily run the turbines at a lower capacity in advance of required maintenance, which would further reduce downtime.

Kongsberg Maritime project manager Oddbjørn Malmo says: “This system will Log in to read complete article.
