本文提出了一种基于超级电容的能量回收系统(ERS)，该系统具有改进的功率控制和能量管理(PC&EM)能力，适用于电梯应用。ERS通过双向DC-DC转换器连接到电梯电机驱动的直流环节，用于存储和回收制动能量。拟议的PC&EM技术通过在预定义的限制范围内通过调节机舱速度来调整电梯功率要求和ERS功率能力，从而提高了成本效益和ERS能力的开发。所提出的控制系统可以很容易地安装，而不需要对电梯电机驱动器进行修改，因此，它可以很容易地应用于任何现有的电梯应用。此外，还提出了一种在线确定和定期微调PC&EM控制器参数的实验方法。本文将所提出的控制技术应用于带非隔离型DC-DC转换器的逆变器中，但也可用于隔离型逆变器中。为了验证所提出的控制技术的有效性，并展示了由此产生的操作改进，给出了选择性的实验结果。
This paper proposes a supercapacitor-based energy recovery system (ERS) with improved power control and energy management (PC&EM) capability for elevator applications. The ERS is connected to the dc link of the elevator motor drive through a bidirectional dc–dc converter for storing and then recovering the braking energy. The proposed PC&EM technique provides improved cost effectiveness and exploitation of the ERS capability, by adjusting the elevator power requirements with the ERS power capability through cabin speed regulation within predefined limits. The proposed control system can be easily installed without requiring modifications in the elevator motor drive, and thus, it can be easily applied to any existing elevator applications. Also, an experimental procedure is proposed in order to online determine and periodically fine-tune the parameters of the suggested PC&EM controller. In this paper, the proposed control technique has been applied in an ERS with a nonisolated dc–dc converter; however, it can as well be used in the isolated counterpart. Selective experimental results are presented in order to verify the effectiveness of the proposed control technique and demonstrate the resulting operational improvements.
