Zusammenfassung:The invention discloses a multi-disaster power transmission line risk assessment method based on a graph theory, and the method comprises the steps: considering the faults, caused by meteorological conditions, of components of a power transmission system, and constructing a risk rating model of a power transmission line based on a graph theory principle and meteorological factors; inputting the basic information of the to-be-evaluated power transmission line into the risk rating model to output a risk grade; when the risk of the power transmission line is assessed through a graph theory method, on the basis of each index, the association degree between a to-be-assessed matter element and an assessment level is obtained by establishing the classical domain and the node domain of the index and the assessment level of an object according to the index weight and the actual value calculation and analysis so as to determine the corresponding risk level of the power transmission line.
