【摘 要】论文首先分析了风力发电的广阔前景,将逐步由补充能源向主力能源发展。其次分析了风力发电机组常见的两种基础形式,即基础环和预应力锚栓的优缺点,并根据分析和实践作出了随着机组大型化趋势的发展,预应力锚栓基础将成为未来的主要基础形式的判断。论文指出防腐技术是预应力锚栓结构面临的一个主要难点,同时总结了当前主要的几种锚栓防腐技术,并最终提出行业内各方应携手加大锚栓防腐技术的研究和经验总结推广,最终形成行业标准的建议。
【Abstract】Firstly, the paper analyzes the broad prospect of wind power generation, which will gradually develop from supplementary energy to main energy. Secondly, this paper analyzes the advantages and disadvantages of two common foundation forms of wind turbines, namely, foundation ring and prestressed anchor bolt, and makes a judgment that prestressed anchor bolt foundation will become the main foundation form in the future with the development of the upsizing trend of wind turbines based on the analysis and practice. This paper points out that anti-corrosion technology is a major difficulty for prestressed anchor bolt structure, summarizes several main anti-corrosion technologies at present, and finally puts forward the suggestion that all parties in the industry should work together to strengthen the research and experience summary promotion of anti-corrosion technology of anchor bolt, and finally forms the industry standard.

1 风力发电是最有前景的可再生能源之一
水电总院郑声安教授谈到,“十三五”前三年,可再生能源增量在全国能源、电力消费增量中分别占40%、38%,可再生能源在能源转型中尚处于增量补充阶段,未来可再生能源将成为我国能源电力消费的增量主体,并为后期逐步实现增量全替代、存量替代做好过渡。预计到2025年可再生能源发电量占全社会用电量比重将达32%左右。
当前,我国能源消费仍以煤炭为主,但煤炭消费占比正在逐年下降,从2011年接近70%,下降到2018年约60%,与此同时,天然气核电、水电、风电等清洁能源消费占比则逐步提升,从2011年的不到15%,增长至2018年接近25%。
按照减排承诺目标,2020年和2030年非化石能源将分别占我国一次能源消费比重的15%和20%。从补充能源向替代能源转变,将是可再生能源发展的总体思路。……
