Modelagem Dinâmica e Controle de Sistemas de Geração de Vapor Baseado em Energia Solar Térmica para Recuperação de Campos de Petróleo

Abstract

In this paper, the control problem of solar thermal recovery plants applied in petroleum fields is studied. In these systems, we aim to maximize the solar energy captured in the collector field and the steam production in order to meet the demand of the injection wells. The proposed control system considers these objectives through a decentralized approach: (i) a PI controller with anticipatory action is used to control the temperature of the heat transfer fluid in the solar field; and (ii) two PID controllers are used to control the liquid level and outlet steam pressure of the steam generator. Simulation results with real data of solar irradiation and ambient temperature are presented to illustrate the efficiency of the proposed strategy.
