The invention discloses an ultra-low frequency oscillation hydroelectric generating set simulation method and device and a storage medium. The method comprises the steps that equipment model parameters of a to-be-tested hydroelectric generating set are acquired; a simulation model of the no-load state of the to-be-tested hydroelectric generating set is constructed according to the equipment modelparameters; the full frequency band of ultra-low frequency oscillation is equally divided into N preset frequency bands, wherein the full frequency band of ultra-low frequency oscillation is 0.01 Hz-0.1 Hz, and N is more than 3 and is less than 10; PID parameters of a speed regulator in the simulation model are set according to each preset frequency band to obtain N sets of set PID parameters; andthe PID parameters of the speed regulator in the simulation model are adjusted to the numerical values of the set PID parameters, so that the simulation model performs time domain simulation verification. According to the met
