24 八 10 Wind turbine must have low voltage ride through capability
Speed development of China’s wind turbine should be said that the first row in the world, Er Jishulaiyuan main Yikaoguowai, Guo Qu wind turbine in the case of small, low-voltage line pairs make different provisions through Gongneng Mo, Mu Qian Yin home wind turbines assembly Jisuduoji number increase, the low voltage power to the fans across the increasingly clear, not long ago, Dian Wang Jiu Guidingwangshang fan Bixujubei low voltage Chuanyuegongneng, the Bu Jin Tigaodianwang quality Geng Zhongyaoyeshi Li Yong of the wind turbine generators plays an important role. European fans have had this technology early, most domestic enterprises are upgrading existing fans and to achieve low-voltage across the function. At present, some enterprises still do not realize this function, and the net will likely be hindered.
Through the ability of low-voltage power system when a larger proportion of stroke power generating capacity, the power system failure resulting in the voltage drop, the wind farms will seriously affect the removal of the system stability, which requires the wind generator with low voltage ride through ( Low Voltage Ride Through, LVRT) capabilities to ensure the system after the failure of wind power grid to run uninterrupted.
