Cables and small converter stations - HVDC Light has great potential for city applications!
As the size of a concentrated load increases due to the on-going urbanization, metropolitan power networks have to be continuously upgraded to meet the demand. Land space being scarce and expensive, substantial difficulties arise whenever new right-of-way is to be secured for the feeding of additional power. Furthermore, with increasing power levels, the risk of exceeding the short-circuit capability of switchgear equipment and other network components becomes a real threat to further expansion.HVDC Light system meets both demands - the cables are easily installed underground using existing right of ways. The capacity can thus be increased on existing power corridors. The HVDC Light converter stations are compact and by virtue of their control, they do not contribute to the short-circuit levels. The controls can furthermore balance power flow on multiple urban infeeds.
