Analysis and research on energy utilization efficiency of port portal crane

Portal crane is one of the important equipment of bulk terminal, which is specially used for shore loading and unloading operation. It mainly consumes electric energy. In order to clarify the utilization of electric energy during the operation of portal crane and analyze the energy utilization efficiency, a portal crane of a bulk terminal was selected as the research object and the energy utilization was tested. The voltage, current, imbalance, harmonic, power and energy efficiency of portal crane were analyzed in his paper. Some suggestions were put forward to improve the energy utilization efficiency and reduce energy consumption of portal crane
