TECHNICAL FIELD

The present invention relates to the technical field of power generation, and specifically to a system for providing mobile power.

BACKGROUND

The oil and gas industry generally adopts hydraulic fracturing to promote the production of hydrocarbon wells (for example, oil or gas wells). Conventional fracturing equipment generally has the problems of occupying a large area, causing severe environmental pollution and so on, failing to satisfy the increasingly serious environmental requirements and the requirements on the area occupied by well-site operations.

A complete set of electric drive fracturing equipment will effectively reduce the discharge of environmental pollutants, the occupied area, noise and the operation and maintenance costs. With the use of a complete set of electric drive fracturing equipment and the continuous increase of the power of the electric drive fracturing equipment, higher requirements are imposed on power supply at the operation site. At the well-site, the power supply for fracturing equipment generally cannot be realized by using a power grid. Moreover, the fracturing operation has the characteristic of short operation cycle, and fracturing equipment needs to be moved among different well-sites. Generally, because various parts of a power supply system require different assembly, transportation and installation processes, the installation time of the power supply system will be up to half to one month.

Therefore, how to provide a mobile power supply system which can be installed quickly and conveniently at the electric drive fracturing operation site is currently a great challenge for electric drive fracturing operations.
