Research on domestic and foreign countries is actively underway to develop OTEC, which boasts an infinite energy source. The MW class OTEC is expected to demonstrate in Kiribati in 2020, and the performance is analyzed through dynamic simulations of extreme conditions that cannot be realized on the experimental plant scale. Simulation conditions were assumed to be flow rate changes of surface water, deep water, and working fluid, and the changes in system power, heat, and temperature were compared during the flow rate change. The heat of evaporator was reduced by about 14.9% and the turbine power was reduced by 150 kW as the surface water flow was reduced by half. In addition, while the deep water flow is reduced by half, 12% of the evaporator heat is reduced and the total power generation is reduced by 200 kW. In the case of working fluid, the flow rate is designed to be reduced to 0, and the output and heat source of heat exchanger are reduced proportionally as the flow rate decreases. The dynamic simulation according to the flow rate will be used to grasp the operating characteristics of OTEC and to be applied for control.
