Method and device for establishing and alarming temperature alarm model of hydroelectric generating set

The invention provides a hydroelectric generating set temperature alarm model establishment and alarm method and device, and relates to the technical field of hydroelectric generating set temperature alarm, and the method comprises the steps: obtaining the historical operation data of a target hydroelectric generating set; determining a plurality of candidate influence factors influencing the temperature of the target hydroelectric generating set based on the historical operation data; processing the historical operation data based on a principal component analysis method to select a target influence factor from the plurality of candidate influence factors; and establishing a temperature alarm model of the target hydroelectric generating set based on the target influence factor. Therefore, the historical operation data is processed based on the principal component analysis method, the target influence factor which has the maximum influence on the temperature of the target hydroelectric generating set is selec
