The invention provides an elevator energy-saving device based on a super capacitor. The elevator energy-saving device comprises a super capacitor bank, a plurality of bidirectional direct-current converters, a plurality of multi-path change-over switches and a super capacitor bank control module, each bidirectional direct-current converter is electrically connected with one super capacitor in the super capacitor group and one multi-path change-over switch; each multi-path change-over switch is electrically connected with frequency converters of a plurality of elevators; the super capacitor bank control module is in signal connection with the plurality of bidirectional direct-current converters, the plurality of multi-path change-over switches and the plurality of linkage elevator control systems respectively; the super-capacitor bank control module adopts a super-capacitor calling algorithm, adjusts routing of a plurality of multi-path change-over switches in real time according to a strategy of minimum super-capacitor bank calling energy consumption, and controls each super-capacitor to be only communicated with a frequency converter of one elevator in the same time period; meanwhile, the path direction of the bidirectional direct current converter is adjusted, and energy is controlled to flow to a certain frequency converter from a certain super capacitor or flow to a certain super capacitor from a certain frequency converter.

    本发明提供一种基于超级电容的电梯节能装置,包括:超级电容组、多个双向直流变换器、多个多路切换开关和超级电容组控制模块;每个双向直流变换器分别与超级电容组中的一个超级电容,以及一个多路切换开关电连接;每个多路切换开关分别与多台电梯的变频器电连接;超级电容组控制模块分别与多个双向直流变换器、多个多路切换开关和多台联动电梯控制系统信号连接;超级电容组控制模块采用超级电容调用算法,按超级电容组调用能耗最小的策略,实时调整多个多路切换开关的选路,控制每个超级电容在同一个时段内仅与一台电梯的变频器连通;同时调整双向直流变换器的通路方向,控制能量从某一超级电容流向某一变频器,或从某一变频器流向某一超级电容。
