The invention provides a mine hoist supercapacitor quick energy storage self-reconfiguration redundant fault tolerant power supply and control thereof, relates to the technical field of a mine hoist self-powering quick energy storage system supercapacitor self-reconfiguration redundant fault tolerant power supply, and particularly relates to the technology of a mine hoist quick energy storage system supercapacitor novel self-reconfiguration redundant fault tolerant power supply. The power supply topology structure and various control modules are introduced, and the control strategies of the power supply under the voltage balance condition and the redundant fault tolerance condition are expressed in a detailed way. The power supply is designed based on single supercapacitors, the performance of each single supercapacitor is monitored in real time through various detection modules, the data are transmitted to a single-chip microcomputer to be analyzed and computed, and the corresponding MOSFET switching tube is controlled to change the structure of the supercapacitor quick energy storage power supply through drive so that redundant fault tolerance and self-reconfiguration quick charge and discharge of the mine hoist supercapacitor quick energy storage power supply can be realized, and the reliability of the mine hoist supercapacitor quick energy storage system can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of supercapacitor self-reconfiguration redundant fault-tolerant power supply for a mine hoist self-generating fast energy storage system, in particular to a new supercapacitor self-reconfiguration redundant fault-tolerant power supply technology for a mine hoist fast energy storage system. Background technique [0002] In the series and parallel supercapacitor groups, there will be voltage balance protection problems when each unit is charged and discharged. However, most of the existing voltage equalization technologies are energy-consuming voltage equalization. In the process of charging and discharging, excess energy is consumed to realize voltage equalization. , discharge). Therefore, the following two situations often occur during the charging and discharging process: first, continue charging, but the monomer is damaged or even spontaneously ignites or explodes; second, the overall charge and discharge...
