Abstract
本发明公开了一种收纳式风力蓄水储能发电系统。该系统根据空气流体动力的特性,通过洞式(或喇叭状)的结构,收纳气流,形成风洞,聚集风力,推动风轮机转动。再以水为介质,由风轮机带动抽水机,抽水蓄能。水进入高水位蓄水库(池)然后以“水力发电”的模式发出电力,水回流至低水位的备水库(池)中。如此,水在系统中往复循环使用。系统克服了现有风能发电技术中靠蓄电池组储能的弊端,提高了风能的利用率,提供了稳定的电力能源。本发明适合在沙漠、戈壁、海滩、岛屿等风力资源丰富的地区建设。对防治沙尘暴等自然灾害有重要作用。
Description
技术领域:本发明涉及的是一种利用率高、发电功率稳定的风能发电系统。对于本系统所发出的电力可并入国家电力网,稳定可靠。可满足电力网的调峰、调谷要求,可调可控、按需发电。按装机容量,多需电则多发电,少需电则少发电,不威胁电网安全。
背景技术:在目前的风能发电技术中,“三叶片”式风机发电是主流,其流程是:风力推动叶片风电机组发电,然后给蓄电池组方阵充电,再经逆变器、变压器等变电设备后,对外供电,或并网。这种技术中存在缺点:
1.所发电力不稳定
由于自然风力的不稳定,导致发电功率出现波动性。发电功率的波动,对蓄电池组有损害,影响蓄电池的使用年限;所发电力的波动,对电力网系统构成威胁和损害,这就是国家长期以来国家电力网对于目前技术状态下的风能、太阳能所发电力表示不喜欢又无奈的原因所在。
2.系统设备需要定期大规模更换
现有技术中的风力发电系统中,风机露天日晒雨淋,容易生锈、损坏;蓄电池组方阵由于反复充放电,容易降低性能,有寿命年限。而更换蓄电池组需要一个昂贵的代价。
3.“三叶片”式风机易破坏生态环境
由于“三叶片”风机露天运转,许多飞鸟被击落身亡,破坏鸟类生态系统,引发一些动物保护组织的抗议。
相比之下:
本发明能很好地解决上述问题,发电系统稳定可控,无需蓄电池组方阵,没有设备大幅更新的情况,一次投入,长期稳定生产。本发明的所有机器设备,大部分是非露天设备,对于生态系统几乎没有影响。
发明内容:
1.为了在一定程度上缓解人类所面临的能源危机,充分利用好地球上巨大的可再生清洁能源——风能。针对现有技术中的缺点,本发明根据空气流体动力的特性,通过洞式(或喇叭式)结构,收纳气流,形成风洞,聚集风力。以水为介质(注:包括淡水、海水、杂质水等液态水),利用风轮机带动抽水机,蓄势储能,然后以“水力发电”的模式,发出电能。水在系统中重复循环使用。
2.与现有的风能发电技术相比,本发明可提供更稳定可靠、灵活可控、持续高效、质优量大,能安全并网的电力。
3.利用本发明在沙漠、石漠、荒漠、戈壁等风力资源丰富的地区大规模发展,在获得优质电力的同时,还有保护环境、培养植被、防风阻沙的功效。对防止沙尘暴等自然灾害有重要作用。
4.利用本发明在海滩、岛屿等海风强烈的地区建设发电站,发展独立的电网,可解决岛屿的用电问题。

图3:本发明的水平式多体风洞结构示意图
图4:本发明的垂直式多体风洞结构示意图
图5:本发明的复式多体风洞结构示意图
具体实施方式:
本发明的实施方式主要有:
1.选址:选择风力资源丰富、风向相对稳定、地势平坦、偏离人口稠密的地点建设。
2.划定区域:按①集风区、②蓄水区、③备水区、④发电区、⑤配送电区、⑥生活办公区六大区域科学建设。
3.建筑设备:采用钢筋水泥砖混结构建设和机械设备的引进组(安)装。
4.强化管理:落实管理措施,确保各种机械设备正常运转,并做好维护检修。
