Abstract:We have studied how to introduce superconducting power cables effectively and economically to a DC electric railway. Numerical analysis models were constructed, and the energy saving by the superconducting power cable was investigated with the influences of the number of substations, the train operation interval, the energy storage, etc. also taken into account. The results show that the superconducting power cables can improve regenerative energy and system energy saving, and reduce the substation capacity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
