The invention discloses a direct-current elevator and a control method thereof.According to the direct-current elevator, a host converter directly connected with a direct-current bus is arranged, direct-current voltage output by the direct-current bus is converted into working voltage of an elevator host, and the direct-current elevator really depends on direct-current driving is achieved; the current value and the voltage value on the direct current bus are detected, and the electric energy fed back to the direct current bus by the elevator host is stored or the voltage on the direct current bus is adjusted according to the current value and the voltage value, so that the problem of feedback energy waste when the direct current elevator is in a generator state is solved; moreover, the dynamic adjustment of the voltage on the DC bus is realized, and the efficient, safe and stable operation of the DC elevator is ensured.
本发明公开了一种直流电梯及其控制方法,该直流电梯通过设置直接与直流母线相连的主机变流器,将直流母线输出的直流电压转换为电梯主机的工作电压,实现真正依靠直流驱动的直流电梯,另外,通过增设与直流母线相连的储能装置,检测直流母线上的电流值和电压值,并根据所述电流值和电压值,存储电梯主机回馈到所述直流母线上的电能,或者,对所述直流母线上的电压进调节,从而解决了直流电梯在发电机状态时回馈能源浪费的问题,并实现了对直流母线上的电压的动态调节,保证了直流电梯高效、安全、稳定的运行。
