China reiterates necessity of LVRT capability for wind turbines (2)

The SERC says that the three incidents indicate that the Chinese wind power industry must reevaluate its turbines and ensure that they will be more secure in the future. The Chinese wind power industry is expected to maintain rapid growth over the next five years.
Over the past five years, China' s wind power industry has realized three-digit annual growth in installed capacity. By the end of 2010, China replaced the United States to become the world' s largest producer of wind power.
Li Yinghua, deputy director of the security regulatory bureau under the SERC, said "It is not an easy task to upgrade existing wind turbines to become LVRT-capable."
"It costs several tens of thousand yuan to upgrade a single wind turbine. This will put considerable pressures on wind turbine makers and wind farm operators to upgrade China's 34,000 wind turbines," said Li.
Li said a new national standard for integrating China's wind farms into the national power grid will be finalized in the first half of this year. Li said that this standard will require these turbines to be LVRT-capable.
