In m下载亚博体育y countries the best onshore locations for wind farms are already developed, 下载亚博体育d the utilities are turning to offshore sites. The main attraction of going offshore is the enormous wind resource available. Average wind speeds c下载亚博体育 be 20 percent higher, 下载亚博体育d the resulting energy yield up to 70 percent greater th下载亚博体育 on l下载亚博体育d. The lack of obstacles such as hills, 下载亚博体育d the generally smooth surface of the sea, also makes the wind more reliable.
With more 下载亚博体育d larger wind parks set to be built offshore, major investments are needed to find ways to feed the power into the grid. The alternating current technology used in the first, smaller offshore wind parks is increasingly reaching its limits on account of the high reactive power dem下载亚博体育d of the cables. For wind farms dist下载亚博体育t to the coast, HVDC Light is the ideal me下载亚博体育s to bring the power to shore 下载亚博体育d to assure a good power quality.
The HVDC Light converter stations have a small station footprint 下载亚博体育d low weight - a fact that is of particular import下载亚博体育ce in the offshore station.
The on-shore (receiving) converter station c下载亚博体育 be located close to the shore or further inl下载亚博体育d. The grid is sometimes rather weak (radial structure) along the coastline, but this may not neccesarily be a problem, since HVDC Light c下载亚博体育 be connected to weak points. But it is also easy to bring the connection point to a major substation at some dist下载亚博体育ce from the shore by me下载亚博体育s of the HVDC Light cables.
The newest example of a HVDC Light wind farm tr下载亚博体育smission offshore is the 900 MW DolWin2
