Figure A-20. Shore-based power plant. 



Fuel consumption necessary to transmit 300 kw 50 miles was 

 approximated to be 7% higher than that necessary to transmit 300 kw 

 10 miles. 



The drip-proof generator would have a remote alarm to indicate 

 overtemperature conditions. The generator output rating would be 300 kw 

 continuous, 4,160 volts, 3 phase, 60 Hertz. A steady-state voltage regulation 

 of 0.25% was considered possible with a generator of this capacity. The diesel 

 engine generator characteristics are listed in Table A-4. 



The shore-based plant could supply a load of 300 kw at distances of 

 10 to 50 miles at 13,800 volts. For the 10-mile distance it was recommended 

 that a 13,800-volt AC system be used, but for the 50-mile distance a 

 13,800-volt DC system was preferred. Since a 300-kw plant for a 50-mile 

 load was selected for preliminary design, a transformer for stepping-up the 

 generated voltage of 4, 160 volts to 13,800 volts, as well as conversion equip- 

 ment to provide DC transmission power, must be provided at the shore plant. 

 Inversion equipment would be required in the load module. A two-conductor, 

 shielded, armored cable with 1/0 AWG conductors would be used for the 

 power transmission cable.
