Subjective–objective methodology on selection of power quality compensation technology in AC–DC network with electrified railways

open access: yesThe Journal of Engineering, 2019
Electrified railways contain DC devices and cause power quality (PQ) issues such as harmonics, unbalance, and low-power factor, which should be solved by the most effective compensation technology to reduce the cost.
