Wind turbine generator systems. The supply chain in China: Status and problems

Wind turbine generator systems (WTGS) manufacture is booming in China. The key to success of the wind turbine generator industry is to construct the supply chain. However few papers focus on the supply chain. In China, many enterprises have started to manufacture the wind turbine generator system and the components. The supply chain of the wind turbine generator system is not well established in China. Many key components of WTGS still need to be imported, such as the principal axis bearing and electrical control systems. We review the status of wind turbine generator system manufacturing and analyze the problems of the supply chain in China. We analyze the problems about the supply chain from a macroscopic view. The aims of this paper are to let more scholars and experts know the status of the WTGS supply chain and to do something for building a successful industry in China.
