The invention discloses an energy-saving elevator control system which comprises an energy-saving module, a frequency conversion module and an elevator body, the energy-saving module is electrically connected with the frequency conversion module, and the frequency conversion module is connected with a power grid and the elevator body. The energy-saving module comprises a super capacitor, a bidirectional DC/DC converter, a main controller and an EPS power supply, the super capacitor is bidirectionally and electrically connected with the bidirectional DC/DC converter, the bidirectional DC/DC converter is bidirectionally and electrically connected with the main controller, the main controller is bidirectionally and electrically connected with the EPS power supply, and the bidirectional DC/DC converter is bidirectionally and electrically connected with the frequency conversion module. According to the energy-saving elevator control system disclosed by the invention, the energy-saving module is additionally arranged, so that the energy consumption of elevator operation is effectively reduced. When the elevator is in a braking state, a heavy-load descending state and a light-load ascending state, the traction machine can generate electric energy, and the electric energy generated by the traction machine is transmitted to the super capacitor through the inverter, the direct-current bus and the bidirectional DC/DC converter to be stored.
