Problems solved by technology

At present, the existing power supply system is mainly powered by a single high-power generator or a combination of power grid and generator. Although the former can meet the maximum power demand of the fracturing well site, the operation of the fracturing well site is usually intermittent. The demand for power consumption between operations is small. During this process, a single high-power generator still needs to consume a lot of fuel when it is idling, so the efficiency is low and the economy is poor; although the latter can adapt to the operating conditions of load power fluctuations, but The lack of unified deployment leads to the generator being in a standby mode with high energy consumption and low output, which also increases the difficulty of operation and use

Abstract

The invention discloses a fracturing well site power supply system, and aims to improve the working efficiency of the fracturing well site and reduce energy consumption while adapting to the working condition of load power fluctuation. The fracturing well site power supply system comprises: a plurality of power supplies; power distribution equipment, wherein the input end of the power distribution equipment is connected with each power supply, the output end of the power distribution equipment is connected to the fracturing well site operation equipment, and the power distribution equipment is used for transmitting electric energy output by the power supplies to the fracturing well site operation equipment and monitoring load state information of the started power supplies; and a first control module respectively connected with each power supply, the power distribution equipment and the fracturing well site operation equipment, and used for determining and starting a first target power supply in the plurality of power supplies based on the total power consumption upper limit of the fracturing well site operation equipment and the power supply upper limit of each power supply before fracturing well site operation, and in the fracturing well site operation gap, determining and shutting down a second target power supply in the enabled power supplies based on load state information of the enabled power supplies.

Description

technical field [0001] The present application relates to the field of petroleum equipment, in particular to a fracturing well site power supply system. Background technique [0002] In the process of on-site drilling, cementing, fracturing and stimulation in the oil field, the electric equipment for on-site operations needs power supply, so a corresponding power supply system is required. At present, the existing power supply system is mainly powered by a single high-power generator or a combination of power grid and generator. Although the former can meet the maximum power demand of the fracturing well site, the operation of the fracturing well site is usually intermittent. The demand for power consumption between operations is small. During this process, a single high-power generator still needs to consume a lot of fuel when it is idling, so the efficiency is low and the economy is poor; although the latter can adapt to the operating conditions of load power fluctuations,...
