The invention relates to the technical field of elevator energy saving, and particularly discloses an elevator control system and method based on a 750V direct-current power supply and an elevator, and the system comprises the 750V direct-current power supply which is connected with a first direct-current frequency converter which comprises a first energy storage device; the power supply conversion module is connected with the 750V direct-current power supply and used for converting the 750V direct-current power supply to obtain a preset voltage power supply, and the voltage of the preset voltage power supply is lower than 750V; the preset voltage power supply is connected with the elevator master controller and used for providing input power for the elevator master controller. The elevator master controller is connected with the first electric energy regeneration device and used for sending a control instruction to the first electric energy regeneration device. And the first electric energy regeneration device inputs regenerated electric energy to the first direct-current frequency converter or the consumption resistor/commercial power. An existing elevator system is improved, and the elevator system based on the direct-current power supply is adopted, so that feedback energy can be fully and effectively utilized, the elevator operation energy consumption is reduced, and the elevator using economical efficiency is improved.

    本发明涉及电梯节能技术领域,具体公开了一种基于750V直流电源的电梯控制系统、电梯控制方法及电梯,系统包括:750V直流电源,与第一直流变频器连接,第一直流变频器包括第一储能装置;电源转换模块,与750V直流电源连接,用于对750V直流电源进行转换处理,获得预设电压电源,预设电压电源的电压低于750V;预设电压电源与电梯主控连接,用于为电梯主控提供输入电源;电梯主控与第一电能再生装置连接,用于向第一电能再生装置发出控制指令;第一电能再生装置向第一直流变频器输入再生电能或向消耗电阻/市电输入再生电能。通过对现有电梯系统进行改进,采用基于直流电源的电梯系统,从而能够充分、有效利用回馈能量,降低电梯运行能耗,提高电梯使用经济性。
