摘要
An elevator automatic rescue and energy-saving control method, the method comprising: when the power grid supplies power normally, selecting a single phase current in a three-phase power grid (9) as an AC power supply for an elevator control system (10); controlling a DC-DC converter (2) to charge the super capacitor module (1) connected to the DC-DC converter to a specified standby electric energy level; and when the power grid is suddenly interrupted, selecting to use the electric energy stored in the super capacitor module (1) as the rescue electric energy for a traction motor (7) and the elevator control system (10). The described method uses a super capacitor module, so that a stable and reliable elevator rescue power supply is provided when the power grid is suddenly interrupted, and the regenerative electric energy dissipated during elevator braking operation is stored and utilized during elevator operation, thereby conserving energy.
