Abstract
A system may include one or more electric hydraulic fracturing rigs, a utility power source, a genset power group that includes gensets, and a site controller configured to receive a total power request for the one or more electric hydraulic fracturing rigs and control, based on a utility power request and a genset power request, the utility power source and the genset power group to power the one or more electric hydraulic fracturing rigs during a fracturing operation.
Claims20
A system comprising:
- one or more electric hydraulic fracturing rigs;
- a utility power source;
- a genset power group that includes gensets;
- and
- a site controller configured to:
- receive a total power request for the one or more electric hydraulic fracturing rigs;
- determine whether only utility power is available;
- when only utility power is available:
- perform a first utility calculation;
- and
- determine, based on the first utility calculation, that a utility power request is equal to the total power request and that a genset power request is equal to zero;
- when utility power is not the only power source available:
- determine whether only the gensets are available as power sources;
- determine, when only the gensets are available, a first number of gensets for the total power request;
- and
- determine, based on the first number of gensets, that a fracturing cost is equal to a genset cost, that the utility power request is equal to zero, and that the genset power request is equal to the total power request;
- when utility power is not the only power source available and when the gensets are not the only power sources available:
- determine a second number of gensets for the total power request;
- perform a second utility calculation;
- and
- determine, based on the second number of gensets and the second utility calculation, the utility power request, the genset power request, and operational parameters;
- and
- control, based on the utility power request and the genset power request, the utility power source and the genset power group to power the one or more electric hydraulic fracturing rigs during a fracturing operation.

- and
- controlling, based on the utility power request and the genset power request, a utility power source and a genset power group that includes the gensets to power the one or more electric hydraulic fracturing rigs during a fracturing operation.
