Abstract
Several large-scale wind turbine tripping accidents occurred in Jiuquan wind power base in 2011. According to the on-site survey and analysis of these accidents related to relay protection, causes were found to be the collection system defects and low correct operation rate of small current grounded line selectors of the unearthed neutral point collection system. By referring to both the characteristics of Jiuquan wind power base and arrangement of relay protection, the short-circuit features of wind power and its impacts on relay protection are analyzed. The collection system and the retrofit of the small current grounded line selector are improved by specific countermeasures. Finally, further research subjects are put forward.
