Abstract
A remote electrical energy generating and distribution system is provided wherein a plurality of combustion turbine generators are located at respective remote sites having deposits of fossil fuel. The fossil fuel is thereby converted into electrical energy for transmission to an energy utilization center or to a power grid. Electrical energy is preferably converted to DC energy at the remote sites, and is supplemented by thermoelectric energy recovered from the exhaust of the combustion turbines. Each such source of DC energy is coupled to a main transmission line by a diode coupling device for providing isolation of each source in the event of a reduction in output voltage. Local power for cooling the diode coupling device is provided by a forward conduction voltage drop within the coupling device. The DC transmission system allows each generator to be operated at any independent optional speed.
