Document Type and Number:
WIPO Patent Application WO/2023/155038
Kind Code:
A1
Abstract:
An electric drive pumping system and a driving method thereof, the electric drive pumping system (100) comprising a power generation device (110), at least one energy storage system (120), a pumping device (140) connected to a main motor (130), an auxiliary device (150), and a first transformer (161). The first transformer comprises an input end, a first output end and a second output end. The energy storage system comprises an energy storage unit (122). The power generation device is connected to the energy storage unit, the input end of the first transformer is connected to the energy storage unit, the first output end of the first transformer is electrically connected to the main motor, and the second output end of the first transformer is electrically connected to the auxiliary device. The electric drive pumping system can avoid the problems of shutdown of a main motor and the like caused by power failure of the power generation device, so as to guarantee continuous operation; in addition, under the condition of a variable load, the power generation device can operate efficiently for a long time, so that the fuel economy is improved.
