The invention discloses a power supply control system. The power supply control system comprises an energy storage power station, a load, an inverter, a main control module, a first switch, a second switch, a third switch and a current detecting unit; the inverter is connected with the energy storage power station and the second switch; the current detecting unit is connected with a mains power supply station and is connected with the second switch through the first switch; the third switch is connected with the first switch, the second switch and the load; the main control module is connectedwith the first switch, the second switch, the third switch, the current detecting unit and the inverter; when current signals detected by the current detecting unit are 0, the main control module controls the inverter to be turned off, and controls the first switch to be switched off, the second switch to be switched on, and the third switch to be switched on, and thereafter controls the inverterto be turned on; when current signals detected by the current detecting unit are not 0, the main control module controls the inverter to be turned off, controls the first switch, the second switch and the third switch to be switched on, and then controls the inverter to be turned on.
Description
【Technical field】 [0001] The invention relates to the technical field of power supply, in particular to a power supply control system. 【Background technique】 [0002] With the rapid rise of renewable energy such as wind energy and solar energy and smart grids, energy storage technology has become the focus of much attention. Distributed energy storage systems have developed rapidly due to their strong ability to adjust microgrid loads and flexible responses in the energy system network. The existing energy storage system, the grid and the load are usually switched and connected manually. The manual switching method makes the human body directly contact with the high voltage, which poses a certain threat to personal safety, and the manual switching is not flexible and fast enough, and the labor cost high. [0003] In view of this, it is necessary to provide a new power supply control system to overcome the above defects. 【Content of invention】 [0004] The purpose of the...
