Siemens installs two test wind power turbines with direct drive technology in Denmark

摘要

Siemens Energy announced that it will test two 3.6-megawatt (Mw) wind turbines with direct drive (DD) technology at a site in west Denmark. The first test turbine was erected in July, with the second to follow later in 2008. Siemens will subject the two DD wind turbines to comprehensive testing for a minimum of two years. The purpose of this project is to assess whether direct drive technology is competitive with geared machines for large turbines. The main advantage of direct drive wind turbines is their smart, straightforward design that makes the use of gearboxes dispensable. With fewer moving parts DD technology has the potential to reduce maintenance costs, which could result in higher turbine availability.
