Switchable apparatus, well site and control method thereof, device, and storage medium

A control method of a well site, comprising:

• providing a plurality of fracturing and power generation switchable apparatus and a manifold connecting therewith, each fracturing and power generation switchable apparatus including a power device, a speed transmission device, connected with the power device, and a bearing base, configured for carrying and fixing a plunger pump or an electric generator, wherein:
• the fracturing and power generation switchable apparatus is configured to switch between a first state and a second state,
• under the first state, the plunger pump is fixed on the bearing base and is connected with the speed transmission device, and the fracturing and power generation switchable apparatus is supplied as a fracturing apparatus;
• under the second state, the electric generator is fixed on the bearing base and is connected with the speed transmission device, and the fracturing and power generation switchable apparatus is supplied as a power generation apparatus;
• the bearing base comprises a first side frame structure and a second side frame structure opposite to the first side frame structure, the first side frame structure and the second side frame structure connected by a plurality of bridging structure;
• each of the first side frame structure and second side frame structure comprising a top supporting plate, a bottom supporting plate, and a relief groove between the top supporting plate and the bottom supporting plate, the relief groove being configured to accommodate a forklift arm;
• and
• the top supporting plate of the first side frame structure and the top supporting plate of the second side frame structure are each bolted with at least a first set of fixing plates for fixing the plunger pump and a second set of fixing plates directly above the relief groove for fixing the electric generator, the method comprising:
• in response to displacement data output by each of the plurality of fracturing and power generation switchable apparatuses in the first state, generating a displacement information, wherein the displacement information comprises the displacement data of each of the plurality of fracturing and power generation switchable apparatuses in the first state and a total displacement value obtained by summing all of the displacement data;
• obtaining a displacement demand input externally,
• when the total displacement value is greater than or equal to the displacement demand, outputting a compliance indication, otherwise, outputting non-compliance indication;
• in response to the compliance indication, based on the displacement information and the displacement demand, selecting at least one candidate switchable apparatus from the plurality of fracturing and power generation switchable apparatuses in the first state and generating a number of the at least one candidate switchable apparatus;
• and
• when the number of the at least one candidate switchable apparatus is greater than a number of electric generators in demand, further selecting a subset of switchable apparatuses with a same number of the electric generators in demand.
