摘要
本文主要阐述了台达能量回馈单元AFE2000在某港口龙门吊的应用。通过AFE2000的高效率能量回馈功能，实现起重机变频器的四象限运行，使用AFE2000替代传统的制动单元和制动电阻，并将重物下降过程中电机发出的电能回馈到电网中去，实现龙门吊最大程度的节能，同时改善了该港口电网的质量。
This article mainly introduces the application of Deha＇s energy feedback unit AFE2000 in the gantry crane of a port. The tour-quadrant operation of the crane＇s frequency converter is realized by means of AFE2000 unit＇s function of high efficient energy feedback and AFE2000 unit can be used to substitute for traditional brake unit and brake resistor and the electric energy is given back to the power grid, which is generated by the crane＇s driving motor during the weight＇s descent process, thus the extreme energy conservation for the gantry crane is achieved, meanwhile the quality of the power grid of the port is improved.
