Ocean Thermal Energy Conversion (OTEC) is an eco-friendly power generation cycle that generates electricity through temperature difference between surface water and deep water, and research is actively conducted to replace the fossil fuel power generation cycle. In this study, for the construction of a scenario for automatic control of OTEC plant, the performance changes of the plant according to changes in surface water temperature were conducted through simulation and experiments. According to the change in surface water temperature, the simulation confirmed that the power generation amount was reduced by 74% and the cycle efficiency by 69%. In the experiment, it was confirmed that the power generation amount decreased by 62% and the efficiency decreased by 42% as the surface water temperature decreased. In order to reduce the difference in results between the actual experiment and the simulation, it is necessary to apply the specifications and performance of the main element devices used in the experiment to the simulation.
