The invention discloses an elevator energy-saving control device and method, and belongs to the technical field of elevator control, and the device comprises a power grid power supply end, a rectification unit, a DC bus, an inversion unit, a traction motor, a super capacitor, and a selection control unit. The method comprises the steps that S1, when the elevator is in the running state, a first switch and a second switch are closed; S2, whether the elevator is in a regeneration running state or not is judged; S3, a third input end communicates with a power supply output end; S4, the charging unit starts to work, S5, the charging unit stops working, and S6, whether the super capacitor is in a power shortage state or not is detected; the beneficial effects are that the situation that the super capacitor cannot continuously store regenerated electric energy due to full charging when the elevator continuously regenerates and operates is avoided, the utilization rate of the regenerated electric energy is improved, and the hardware cost is reduced.
本发明公开了一种电梯节能控制装置及方法,属于电梯控制技术领域,装置包括:电网电源端、整流单元、直流母线、逆变单元、曳引电机、超级电容、选择控制单元;方法包括:步骤S1,于电梯处于运行状态时闭合第一开关和第二开关;步骤S2,判断电梯是否处于再生运行状态:步骤S3,将第三输入端与电源输出端连通;步骤S4,充电单元开始工作,步骤S5,充电单元停止工作,步骤S6,检测超级电容的是否处于缺电状态;有益效果是:避免了电梯在连续再生运行时,超级电容因充满而无法继续存储再生电能,提高了再生电能的利用率,节约了硬件成本。
