Zusammenfassung:	The invention relates to the technical field of power grid power transmission, and discloses a state diagnosis method based on power grid power transmission. Analyzing and processing the transmission duration of the power grid in the acquired historical data to obtain a historical vibration parameter value and a historical loss parameter value of the power grid transmission line; a historical vibration parameter value of a power grid transmission line and a historical loss parameter value element of the power grid transmission line are obtained. According to the method, the historical data are collected and further analyzed and processed, so that the historical loss parameter value and the historical vibration parameter value of the power grid transmission line are obtained, and the power grid transmission line is determined based on the obtained historical loss parameter value and the historical vibration parameter value. And judging whether the loss of the line is influenced by the vibration of the line dur
