为了缓解我国淡水缺乏的现状，将海水进行淡化成了一个主要的研究方向。针对传统海水淡化方法属高耗能产业，并且使用常规能源，对环境易造成二次污染的缺陷，介绍了一种基于非并网多能源协同供电的海水淡化系统。该系统基于非并网风电原理，利用风、光、潮汐等绿色能源对海水淡化系统供电，提高了能源的利用效率，实现二氧化碳的零排放，具有很好的社会经济效益。本文设计并研发了一套单台风机日产万吨海水淡化系统，该系统利用1台2.5 MW风机对海水淡化系统供电，基于非并网风电理论，做到了风电高效、低成本、全部利用。

To alleviate the current situation of our country for lack of fresh water， seawater desalination has become a major research direction. According to traditional desalination is high energy-consuming industries， and uses conventional energy， which could easily lead to secondary pollution for environment， a seawater desalination system using non-grid-connected multi-energy collaborative supply is proposed in this article. The system bases on non-grid-connected theory， wind， light， tidal and other green energy is utilized to power seawater desalination system， which can improve the efficiency of energy use and achieve zero emissions of carbon dioxide. The system possesses good social and economic benefits.
