Rapid expansion of wind power generators installed capacity

Rapid expansion of wind power generators installed capacity, accidents continue to cause transformation of the converter needs. According to the Chinese Wind Energy Association, as of 2010, China's total wind power installed capacity has reached 44.73GW, relative to the amount of technology can develop 297GW, development has reached 15.1%. According to the plan, China's wind power by 2015 will exceed 90GW, will reach 150GW by 2020 or more. Although China's wind power industry maintained rapid growth for nearly 10 years, but due to lack of low-voltage ride through capability, massive fan off the net thing it caused a huge impact on the grid. Currently the majority of fans are not running the installation of low wind generators voltage across the module, there are also some of the previous installation can not meet the EPRI [39.48 -1.30% stock research reports it] the latest requirements, continue to occur it will be off the net thing lead converter transformation needs.

Industry gave birth to windmill power rectification converter broad market. Since August this year began, the SERC organize safety inspections of wind power, windmill generator equipment in one of the most important thing is to check the unit low voltage ride through capability of detection and transformation. Since then the Department of Energy issued "large-scale wind farms and network design and technical specifications" and other 18 key standards, including low-voltage ride through capability of the fan. According to our estimates, the converter will bring 30 billion transformation of new market space. Moreover, since the transformation of the gross margin levels are relatively higher converter machine, so the firms would be more benefit. We expect that the future will further the issue of low voltage through the concentration and control, through do not have the low voltage ride through capability of the unit for rectification, so as to effectively prevent the fan hanging net thing it's happening again.
