Description

technical field

[0001] The invention relates to a charging and discharging power supply device, in particular to a device that combines wind power and solar energy for redundant power generation and provides electric energy for a wellhead safety control system. Background technique

[0002] Oil and natural gas are often distributed in deserts, oceans and other areas that are not covered by the power grid. Therefore, in areas far away from the power grid, even in some severe weather environments, it is impossible to normally provide electrical equipment for the wellhead safety control system of oil and gas production equipment. powered by. In the prior art, the traditional method is to use solar power to generate power for the wellhead safety control system. Specifically, the solar power supply device is composed of a solar panel, a charging and discharging controller and a storage battery.

[0003] However, the disadvantage of this method is mainly limited by the sunshine ...
