Abstract
A system for utilizing coal energy includes a thermal power generator near a coal field area that converts coal energy of the coal field area located remotely from a demand end to electric energy. It also includes an alternating current load at a demand end side, an alternating current power distribution network, and an electric power transmission mechanism that transmit electric energy from the thermal power generator to the power distribution network. The electric power transmission mechanism is a combination of super conductive power transmitting system that transmit direct current electricity with small transmission loss utilizing super conductive power transmitting cables and a conventional power distribution network operating at ambient temperatures.
