Abstract

Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevertheless, PV/T based RO plants should be controlled in order to solve operation problems related to electrical efficiency, reverse osmosis membrane, produced water and the rejected salts. This paper suggests a fuzzy logic controller for the flow rate of the circulating fluid into the PV/T collectors so as to ameliorate the system performances. The designed controller has improved the PV/T field electrical efficiency and preserved the reverse osmosis membrane which upgrades the system productivity. LABVIEW software is used to simulate the controlled system and validate the effectiveness of the controller.
利用模糊控制器改进PV/T反渗透海水淡化装置性能
基于光伏的反渗透海水淡化系统(PV/RO)是一种有效的海水淡化方法,特别是在偏远地区。提高进水温度可以改善装置的性能。光伏集热器(PV/T)为反渗透过程提供电能和热能,是一种理想的电源。然而,为了解决与电效率、反渗透膜、产出水和废盐相关的操作问题,应该控制PV/T RO装置。本文提出了一种用于PV/T集热器循环流体流量的模糊控制器,以改善系统性能。设计的控制器提高了PV/T现场电效率,并保留了反渗透膜,提高了系统的生产效率。利用LABVIEW软件对被控系统进行仿真,验证了控制器的有效性。
