wherein the plurality of fracturing power sources comprise at least two distinct types power system.

2 . The fracturing system of claim 1 , wherein the plurality of fracturing pumps comprise a plurality of plunger pumps.

3 . The fracturing system of claim 1 , wherein the plurality of fracturing power sources comprises at least one turbine engine or at least one electric motor.

4 . The fracturing system of claim 1 , wherein the plurality of fracturing power sources comprises at least one turbine engine or at least one diesel engine.

5 . The fracturing system of claim 1 , wherein the plurality of fracturing power sources comprises at least one electric motor and at last one diesel engine.

6 . The fracturing system of claim 1 , wherein the plurality of fracturing power sources comprises at least one turbine engine, at least one electric motor, or at least one diesel engine.

7 . The fracturing system of claim 1 , wherein
the plurality of fracturing power sources comprises one or more turbine engines;
power of at least one of the one or more turbine engines is split off to power an electric generator to drive at least a portion of the auxiliary system.

8 . The fracturing system of claim 7 , wherein the electric generator is powered by the at least one of the one or more turbine engines after a speed reducer or a gearbox.

9 . The fracturing system of claim 1 , wherein

10 . The fracturing system of claim 9 , wherein the hydraulic system is powered by the at least one of the one or more turbine engines after a speed reducer or a gearbox.

11 . The fracturing system of claim 1 , wherein
the plurality of fracturing power sources comprises one or more diesel engines;
power of at least one of the one or more diesel engines is split off to power an electric generator to drive at least a portion of the auxiliary system.

12 . The fracturing system of claim 1 , wherein
the plurality of fracturing power sources comprises one or more diesel engines;
power of at least one of the one or more diesel engines is split off to power a hydraulic system to drive at least a portion of the auxiliary system.

13 . The fracturing system of claim 1 , further comprising a diesel engine for powering an electric generator to supply power to at least a portion of the auxiliary system.

14 . The fracturing system of claim 1 , further comprising a diesel engine for powering a hydraulic system drive at least a portion of the auxiliary system.

15 . The fracturing system of claim 1 , wherein the auxiliary system is powered by dedicated an external electric source.

16 . The fracturing system of claim 1 , further comprising at least one or more subsystems, each of the one or more subsystems belonging to one of a chemical adding subsystem, a sand mixing subsystem, a sand conveying subsystem, and a fracturing fluid mixing subsystem.

17 . The fracturing system of claim 16 , wherein at least one of the one or more subsystems is powered by a dedicated external electric source.

18 . The fracturing system of claim 16 , wherein at least one of the one or more subsystems is powered by electric power generated by a split off power from at least one of the plurality of fracturing power sources.

19 . The fracturing system of claim 16 , wherein at least one of the one or more subsystems is powered by a hydraulic system driven by a split off power from at least one of the plurality of fracturing power sources.

20 . The fracturing system of claim 16 , wherein at least one of the one or more subsystems is powered by an electric power from an electric generator driven by a diesel engine.
