Abstract
An electrically driven fracturing system is provided. The electrically driven fracturing system includes: one or more frequency converter apparatuses; and a plurality of electrically driven fracturing apparatuses configured to pressurize and output fluid. One of the one or more frequency converter apparatuses is connected with multiple ones of the plurality of electrically driven fracturing apparatuses, respectively, and the frequency converter apparatus is configured to adjust pressure and flow rate of fluid output by the multiple electrically driven fracturing apparatuses.
Claims20
An electrically-driven fracturing system, comprising:
- a plurality of frequency converter apparatuses;
- a plurality of electrically-driven fracturing apparatuses and configured to output pressurized fracturing fluid;
- and
- a centralized control system, wherein:
- each of the plurality of frequency converter apparatuses is correspondingly connected to at least one electrically-driven fracturing apparatus of the plurality of electrically-driven fracturing apparatuses, and comprises a frequency conversion control system to form a plurality of frequency conversion control systems,
- each of the plurality of electrically-driven fracturing apparatuses comprises an electric motor, and a fracturing control system to form a plurality of fracturing control systems,
- the centralized control system is in communicating connection with the fracturing control systems such that the centralized control system and the fracturing control systems form a loop structure in which the fracturing control systems are connected in series with each other and with the centralized control system,
- the centralized control system is in communicative connection with the frequency conversion control systems via one or more of the fracturing control systems, and
- each of the plurality of frequency converter apparatuses is configured to adjust a rotating speed of the electric motor by adjusting a frequency of the electric motor to adjust pressure and flow rate of the pressurized fracturing fluid.
