Abstract

本发明公开了一种由水库、海堤、泵、管道组成的海潮式抽水蓄能技术,泵在海洋潮汐涨至高潮时与水库水位相持平时,泵向水库抽水蓄能,低潮时放水发电。由于泵抽水蓄能所耗电能小于低潮时放水发电所获电能,故在抽水蓄能转换过程中,有良好的能源效益。

Description

海潮式抽水蓄能
技术领域
本发明涉及一种抽水蓄能,特别是涉及一种海洋潮汐抽水蓄能。
背景技术
目前有各种各样的蓄能方式,如抽水蓄能,电池蓄能等蓄能技术,这些蓄能技术在蓄能过程中都有一定的能量损耗,鲜见海洋潮汐高潮时抽水蓄能,低潮时放水发电的蓄能技术。一种公知的抽水蓄能电站(如图1所示)是将用电低谷多余的电能抽水蓄能,待用电高峰时放水发电来调剂用电高峰在电能需求,在用电低谷将水库2的水经管道4由水泵水轮机3抽水至水库1蓄能,当用电高峰将水库1的水下放流过水泵水轮机3带动发电机发电,尾水流入水库2。
发明内容
本发明的目的在于提供一种:海洋潮汐涨至高潮时抽水蓄能,所耗电能小于低潮放水发电所获电能的海潮式抽水蓄能技术。
为了达到目的本发明的解决方案是:海潮式抽水蓄能是由海堤、管道、水库、泵组成。泵安装在海堤上,泵与接入海洋的管道相接,海洋潮汐高潮与水库水位相持平时,泵向水库抽水蓄能;低潮时放水发电。由于泵是高潮水位时工作,泵的工作扬程(水头)小于潮差,故泵的工作能耗小于蓄能发电所获取的电能。本发明充分利用涨潮与落潮的水头变化,进行抽水蓄能发电,在能量的转换过程中获取良好的能源效益。
下面结合附图和具体实施例对本发明作进一步的说明附图说明图1为一种公知的抽水蓄能发电站图2为本发明实施例的结构示意图
具体实施方式
如图2所示,本发明海潮式抽水蓄能的实施例,它是由泵1、管道2、海堤3、水库4组成;海堤3将海洋与水库4隔断,海洋与水库4之间的海堤3有阐(阀)控制海水互通,所述泵1的工作扬程小于潮差,泵1是在高潮与水库4水位相持平时抽水蓄能;泵1的工作扬程越低,潮差与泵1扬程之比就越大,转换的电能效率就会增高。
实施例工作原理海洋潮汐涨至高潮与水库4水位相持平时,泵1从海洋向水库4抽水蓄能,当潮汐落至低潮时放水发电。
