13. A fracturing system, comprising:
a plurality of fracturing pump sets; and
a fracturing control device coupled to the plurality of fracturing pump sets, wherein the fracturing control device is configured to:
turn on a first fracturing pump set of the plurality of fracturing pump sets according to a total required output of the fracturing system;
adjust an operating parameter of the first fracturing pump set according to an actual output of the first fracturing pump set and an output threshold corresponding to the first fracturing pump set, so that the actual output of the first fracturing pump set is an operating output, the operating output being f1 times the output threshold, wherein f1 is a number;
when the operating output of the first fracturing pump set is less than the total required output, turn on a second fracturing pump set of the plurality of fracturing pump sets, and a priority of turning on the second fracturing pump set being lower than a priority of turning on the first fracturing pump set;
obtain an amount of energy consumed by at least one fracturing pump that is turned on in the first fracturing pump set; and
when the amount of energy consumed by the at least one fracturing pump that is turned on in the first fracturing pump set is greater than or equal to an energy threshold corresponding to the first fracturing pump set, turn off the at least one fracturing pump that is turned on in the first fracturing pump set.
