Construction of Simple Dynamic Model for OTEC Plant Using Rankine Cycle

Abstract

In this paper, a simple dynamic model for an OTEC plant using Rankine cycle is constructed. The proposed dynamic model consists of steady state calculation of state quantity based on mass balance and energy balance, and transient calculation of the heat exchanger dynamics. The proposed dynamic model can express both the steady state and the transient state of the OTEC plant. Moreover,evaluation indexes of the OTEC plant are obtained. Accuracy of the proposed dynamic model is evaluated by comparing with experimental results of an OTEC pilot plant.
