摘　　要：为了能够快速有效地利用门式起重机在起重工作机构下降及减速制动时产生的能量,研制出了一种基于超级电容储能的势能再回收系统。该系统充分利用超级电容大功率快速充放电的特性,通过双向DC/DC功率单元快速回收起重机构的下降势能,并作为起重机构上升时所需的能量补给,可降低起重机工作能耗,提高能量利用率,达到节能降耗的目的。A potential energy recycling system based on super capacitor energy storage is developed to rapidly and effectively capitalize on the energy generated by the hoisting mechanism of portal cranes during lowering and retarding braking. The system fully utilizes characteristics of super capacitors, or high-power rapid charging and discharging, to swiftly recycle the potential energy generated at lowering through two-way DC/DC power unit, and the recycled energy is reused for lifting, which promises lower energy consumption and higher energy utilization for cranes, achieving the goal of saving energy and reducing consumption.
