Several large-scaRe wind turbine tripping accidents occurred in Jiuquan wind power base in 2011. Combining with the characteristics of large-scale wind power and its integration arrangement, and configuration of relaying protection, the existing problems are investigated. On this basis the uncertainties of wind power, fault location and transition resistance and its impacts on relay devices fitted on different power equipment are further analyzed. The improvement of collector system and relay devices and the collection and analysis of recorded fault data of wind farm and its integration system are proposed, and finally the subjects of further research such as fault analysis tool, fa
