Fuzzy fault tree analysis of power project safety risk for the smart construction

All risk events of power grid usually show the complex logic relation of the factors caused by the disaster. This paper analyzed the fault reasons based on the systematology, and proposed the fuzzy fault tree model of power project in the smart construction, and distinguished the safety risk of the transmission tower collapses. It realized that the fault probability caused by the strong storm is undefined, and this paper regards the probability of the basic event as fuzzy datum, and calculated the occurrence probability of transmission tower collapses based on the fault tree logic structure analysis of intermediate and top events. The applied example shows that it is possible applicable to using the fuzzy fault tree method to analyze the safety risk of the tower collapse accidents of power project.
