ABB powers China's first offshore wind farms

168 turbines at two offshore wind power sites will be equipped with ABB's SafeRing/SafePlus gas-insulated RMU and switchgear technology.


China has officially announced that it is committed toproducing at least 100 gigawatts of offshore wind power by 2020. To reach thisgoal, the first two installations in what is probably the world's largest cleanenergy project -- the 102 megawatt (MW) Donghai Bridge and the 201 MW JiangsuXiangshui -- are nearing completion. All 168 turbines across these two projectswill be equipped with ABB power products.

With a 14,500-kilometer coastline and most of its population

centers and manufacturing zones clustered along the seaboard, China has a

huge potential and ready market for converting offshore wind into emission-free


Jiangsu province in particular, which lies north of

Shanghai, has been designated by the government as the country's main offshore

wind power location, and it is here, in both Jiangsu and Shanghai, that the

country's first two installations are located. The 102 MW Shanghai Donghai Bridge will consist of 34 turbines, each

with a rated output of 3 MW; and the Jiangsu Xiangshui project will comprise

134 1.5 MW turbines. Both parks are scheduled to be fully operational by 2010

and 2011 respectively.

ABB products used in these two projects comprise a

complete and integrated ring main unit (RMU) and switchgear solution. These

products are considered critical to the protection of the turbine electrical

systems, and ABB says it has customized the products for these projects to the

needs of China's

offshore wind power market.

Based on ABB's SafeRing/SafePlus gas-insulated RMU

and switchgear technology, the solution is reported to be half the size of

conventional alternatives. ABB says its SafeRing/SafePlus products are built to

withstand the corrosive effects of the harsh offshore environment without

scheduled maintenance and offer low environmental impact -- the components are

reportedly 98% recyclable.) The SafeRing/SafePlus products are delivered to the sites as a completely sealed system with a stainless

steel tank containing all the live parts and the switching equipment.
