MARINE POWER SUPPLY SYSTEM, VESSEL EQUIPPED WITH SAME, MARINE POWER SUPPLY SYSTEM CONTROL METHOD, AND MARINE POWER SUPPLY SYSTEM CONTROL PROGRAM

摘要

The purpose of the present invention is to provide a marine power supply system which comprises a diesel generator, an Organic Rankine Cycle system, and a secondary battery and runs the diesel generator under high load and to provide a vessel equipped with the marine power supply system, a marine power supply system control method, and a marine power supply system control program. Provided is a marine power supply system (1) having a control device (9) which performs control for combining a diesel generator (10), an ORC system (2), and a secondary battery (20) in order to meet onboard power demand, wherein the diesel generator (10) has a load factor in the range of 60-90% with respect to the average onboard power demand, the control device (9) performs control so that the secondary battery (20) is charged with surplus power if the onboard power demand does not exceed the total output of the diesel generator (10) and the ORC system (2) and performs control so that the power stored in the secondary battery (20) is discharged if the onboard power demand exceeds the total output of the diesel generator (10) and the ORC system (2).
