Abstract
A device and method for starting a pumped storage group, and a pumped storage system are disclosed. The device includes: an acquisition module configured to acquire starting data of the group in real time; a first determination module configured to determine a real-time speed versus time curve for the group based on the starting data; and a correction module configured to correct a starting speed of the group based on a deviation between a reference speed versus time curve cluster and the real-time speed versus time curve. The real-time speed of the group during starting is visualized through a curve fitting procedure to form the real-time speed versus time curve, the real-time speed versus time curve is compared with a favorable history operation curve, and the deviation between the real-time speed versus time curve and the favorable history operation curve is corrected to adjust the starting speed of the group.
