超级电容储能装置在电梯中的研究与实现

摘要

The super capacitor energy storage device to recycle the application of elevator brake power is described. During the running of the elevator,the fluctuation of DC bus voltage is great, this will impact on grid greatly, especially on energy feedback. It will disturb users' electricity distribution system and endanger the operation of power system.The bi-directional DC/DC converter based on the super capacitor energy storage is applied to resolve the problems above, its composition and principle are analyzed.At last, the feasibility of this converter is verified by experiment.%研究了超级电容储能装置在回收利用电梯制动能量方面的应用.电梯在运行过程中的母线电压波动较大,因而会对电网造成较大冲击,尤其是在能量回馈时,对用户配电系统造成较大扰动,危害了电力系统的安全运行.此处提出采用基于双向直流变换器的超级电容储能装置解决上述问题,并对其工作原理进行了分析,最后通过实验验证了方案的可行性.
