Energy Control and Optimization of Hybrid Load-Haul-Dump

Abstract:

Hybrid technology is widely recognized as the most effective measure to reduce the fuel consumption in Load-Haul-Dump (LHD). Using a hybrid power system on LHD is proposed. This comprises an internal combustion engine and super capacitor. LHD has the characteristics of duty cycle. Based on the characteristics we get the hydraulic power demand,electric transmission power demand. We propose an energy control strategy to reasonably distribute power of hybrid energy sources. With the help of control strategy, super capacitor can be restricted to work in a pre-defined range of SOC characterized by higher efficiency region. We also analyze the super capacitor charging/discharging process. In order to realize the fuel economy fullest, we optimize the design parameter using the simulated annealing algorithm. The simulation results show that improvement in fuel economy was about 11.3% better than that of before the optimization.
