起重设备能量回馈系统研究

A Research on the Energy-Feedback System of Crane Equipment

传统的起重设备采用能耗制动的方式把电机回馈的能量消耗掉,而把这部分再生能量反馈到电网重新利用无疑具有节约用电的功效.文章就如何实现起重设备的能量回馈系统进行研究,其中的一些方法值得业内同仁参考.

Traditional crane equipments consume the motor feedback energy by means of dynamic braking.But undoubtedly,it will save energy if the regenerative energy can be optimally restored to the power system.The article studies the crane equipments energy-feedback system in terms of the optimal energy-feedback methods.Some of the methods discussed is of reference value.
