摘要

为了节省电梯的能量，目前研究最多的方法是采用由双向DC/DC变换器和超级电容器组成的储能系统。该超级电容器可以在再生模式下有效地利用再生电能，并在运动模式下进行放电。通过对电梯交通流模型的分析，提出了一种基于交通流差异的电容设计方法，既能满足电梯运行安全要求，又能降低系统成本。然后，通过分析直流母线电压检测的能量管理策略，分别分析了电机模式、再生模式和故障模式的控制策略。最后搭建了超级电容储能式电梯实验平台。实验结果验证了系统控制策略能有效地利用和分配所利用的能量。

Analysis of energy management strategy for energy-storage type elevator based on supercapacitor

In order to save the elevator energy, the most researched method is adopting the energy storage system composed of a bidirectional DC/DC converter along with supercapacitor. The supercapacitor can effectively harness the regenerated electric power in the regenerating mode and discharge it in the motoring mode. By analyzing traffic flow model of elevators, a capacitance design method based on traffic flow difference is proposed in this paper, which can satisfy the elevator operational safety requirements and reduce the system cost. Then, control strategies of motoring mode, regenerating mode and malfunction mode are analyzed respectively by analyzing energy management strategy of DC bus voltage detection. Finally, an experimental platform of supercapacitor energy-storage type elevator was built. Experimental results validate that the system control strategy can effectively harness and allocate the harnessed energy.
