Design of a Hybrid Electric Power-Split Transmission for Braking Energy Recovery in a Drilling Rig

Despite the promising potential of hybrid electric power-split layout, its broader market penetration is prevented by large number feasible solutions and constructive complexity, which overcomplicate design process. Moreover, due to lack relevant literature references, transmissions even more difficult if concerning applications outside automotive agricultural sectors. In this paper, a general parametric model already available in single-mode transmission with up two planetary gear sets six ordinary was applied hybridize an oil drilling rig recover energy braking during gravity-driven lowering phases. This first hybridization rig. Two differing engine power size are presented. Thanks modularity model, procedure enabled optimization ICE, machines, through decoupled
