1. A turbine fracturing system, comprising:
N turbine fracturing apparatuses, wherein each of the N turbine fracturing apparatuses comprises a turbine engine, and N is an integer greater than or equal to 2;
a fuel gas supply apparatus connected to N turbine engines, wherein the fuel gas supply apparatus is configured to supply a fuel gas and distribute the fuel gas to the N turbine engines as gaseous fuel;
a fuel liquid supply apparatus connected to at least one of the N turbine engines and configured to supply liquid fuel to at least one of the N turbine engines when at least one of a flow rate and a pressure of the fuel gas decreases; and
a measurement and control apparatus comprising a data acquisition device and a data processing device,
wherein the data acquisition device is in signal connection with the fuel gas supply apparatus, and configured to acquire first fuel gas data of the fuel gas and send the first fuel gas data to the data processing device; and
the data processing device comprises:
a comparison and determination circuit in signal connection with the data acquisition device and configured to compare the first fuel gas data with a first threshold value and determine whether the first fuel gas data is smaller than the first threshold value, the first fuel gas data comprising the at least one of the pressure and the flow rate of the fuel gas, and the first threshold value comprising at least one of a first pressure threshold value corresponding to the pressure and a first flow rate threshold value corresponding to the flow rate; and
a control circuit in signal connection with the comparison and determination circuit, wherein the control circuit is configured to select the at least one of the N turbine engines and generate a first fuel switching signal in response to the first fuel gas data being smaller than the first threshold value; the first fuel switching signal is used for switching the gaseous fuel of the at least one of the N turbine engines into liquid fuel.
