전기굴삭기 효율향상을 위한 전기동력시스템 동작점 제어알고리즘 연구

A Study to Improve Efficiency of Electric Power System for Electric Excavator

초록

The working time of electric excavator needs to be extended by improving efficiency of the electric power system. In this paper, the characteristics and efficiency maps of tandem pump-electric motor system is analyzed and the control algorithm which optimize the displacements of the tandem pump is established. To confirm the utility of this algorithm, the model-in-the-loop simulator of electric excavator for the algorithm is established. The simulation results shows that the control algorithm improved the energy efficiency of the electric excavator.
