Model Construction of OTEC Plant Using Double-stage Rankine Cycle with Time Delay by Considering Separator and Working Fluid Tank

In this research, a model for ocean thermal energy conversion (OTEC) plant using double-stage Rankine cycle to take time delays into account is proposed. The model is constructed by combining the conventional model with the characteristics of separator and working fluid tank. In order to confirm the effectiveness of the proposed model with time delays, a numerical simulation was carried out. The simulation result indicates that the time delays were successfully reflected on most of the calculated results.
