Global Wind Generator Production Trajectory â€“ Staggering Growth With 29% CAGR During 2009-2020
Online PR News – 29-December-2010 – – Emerging as a feasible alternative to fossil fuels, wind energy is being increasingly utilized, due to its economic viability compared to other renewable forms of energy and because itâ€™s cleaner than conventional energy sources. This growth trajectory in the wind energy industry is being primarily led by the US, China, Germany and Spain, which together accounted for 66% of global cumulative installed wind generator capacity in 2009. These countries are riding on the growth wave of the wind energy industry. The industry witnessed a growth rate of 38% during 2008-09 in cumulative installed capacity and along with it; there was also a significant growth in components such as wind generators. Demand for wind generators in the booming wind markets - the US, Europe and China - continue to increase. The global wind generator production grew at a Compound Annual Growth Rate (CAGR) of 29%, from 18,000 Megawatts (MW) in 2006 to 35,398MW in 2009. The wind generator production globally is expected to reach 67,403MW by 2020, at a CAGR of 6% during the period 2009 and 2020.

Utilization of direct-drive, grid connected generators in wind generation is expected to grow in the future. future trend . The elimination of gear boxes and power electronic converters will significantly increase system reliability. The overall system efficiency will increase because the losses in the gear box and power electronic converters are eliminated. The power loss in the gear box accounts for a fairly high proportion of the total wind turbine system loss, and thus reduces efficiency.
Additionally, gearbox reliability has been a major issue. And each time a gearbox is replaced, it is a major expense for wind turbine generators. But direct-drive generators eliminate this issue by removing the gearbox entirely. The direct-drive approach was successfully adopted long ago by Enercon and is being examined by other turbine manufacturers. Modular (transportable) and maintenance-friendly versions of these large generation systems will go a long way in making the low-wind portion of the power curve much more productive. Though direct-drive generators have a number of advantages, it is difficult to comprehend in which direction the electric generators used in wind turbine is expected to move. geared generators have their distinctive advantages too. And therefore, it cannot be said with certainty whether the market for direct drive generators will grow more than geared generators or vice versa.
