摘要

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。

Improvement of PV/T Based Reverse Osmosis Desalination Plant Performances Using Fuzzy Logic Controller
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.
