Description

风能、潮汐能互补蓄能发电系统
技术领域
本发明涉及一种风能、潮汐能互补蓄能发电系统。 
背景技术
风能、潮汐能是不消耗化石能源，不排放温室气体和二氧化碳的可再生清洁能源，虽然风能、潮汐能转换成电能的技术日臻成熟，其经济性也逐渐接近传统电能生产成本，为人们所接受，但由于风能、潮汐能其自生不可控的自然规律，在能量转换过程中，电能不能储存，风能、潮汐能转换成电能时，在电网的低谷期不能即时消纳，造成风能、潮汐能所转换成的电能单位电价偏高，虽然有清洁能源优势，在电价经济指标上尚有不足之处。 
我们日常生活、生产的用电过程，在昼夜的时限内，会产生白天的用电高峰期和夜晚的用电低谷期，即业内所称的电网峰电和谷电，峰电缺口大时，就要增加电能的生产，传统的措施是建发电企业加大产能，增加电能供给，这就更加大了电能与电力的矛盾。目前比较有效的方法是建设抽水蓄能电站，用夜晚用电低谷富余的电能与电力产能，将下水库的水提升到上水库，以势能形式存储，白天用电高峰时抽水蓄能电站高位势能的水，转换成电能削峰填谷，化解电能与电力矛盾。但抽水蓄能电站的选址十分苛刻，既要有近距离适宜建筑上、下水库的地形，又要有充足的水源和水量，还要具有大容量双向输、送电设施，建设初始投资巨大，技术要求严格，由谷电转换成峰电的效率仅在百分之五十左右，抽水蓄能时所消耗的大量电能，同样排放温室气体 
风能、潮汐能以风力发电机和潮汐电站技术转换成电能时，同样在电网形成峰电和谷电，特别是潮汐电站只有在一昼夜的両次涨潮时，拦截在潮汐电站水库内的海水，在低潮位时才能排水发电，其中一次的排水发电就是在电网的用电低谷期，风力发电机同样在一昼夜的周期内，在电网用电低谷期，由于夜间海上与陆上的温差大，风力比白天丰富，发电效率最佳，但对电网峰电的用电需求贡献并不大。。 
发明内容
本发明所要解决的技术问题就是为了克服上述现有技术存在的缺陷而提供一种风能、潮汐能互补蓄能发电系统。本系统利用风力发电机和潮汐电站电网用电低谷期所产的低值电能，将涨潮时已在高位的海水，提升至更高位的蓄能电站水库，待海水退潮低潮位时，蓄能电站水库内存储的海水势能大幅度增加，电网用电高峰期时风力发电机、潮汐电站、抽水蓄能电站可同时向电网送电，达到利用清洁电能截留非拦蓄海水的势能，增加电网峰电清洁电能有效供给的目的。 
本发明的目的可以通过以下技术方案来实现：风能、潮汐能互补蓄能发电系统，包括智能控制器、风力发电机组、潮汐电站及机组、抽水蓄能电站及机组，所述的抽水蓄能电站水库坝底海拔高度高于潮汐电站坝顶海拔高度，风力发电机组经换向开关分别与抽水蓄能电站抽水机组或变压器连接，潮汐电站机组经换向开关分别与抽水蓄能电站抽水机组或变压器连接，所述的智能调控器分别与风力发电机组、潮汐电站及机组、抽水蓄能电站及机组连接。 
所述的潮汐电站及机组、抽水蓄能电站及机组，为同一水系的上下两个水库电站。
所述的抽水蓄能电站机组为发电＝抽水两用可逆机组。 
与现有技术相比，本发明通过智能调控器控制，将风力发电机组和潮汐电站在电网用电高峰期直接连接变压器向电网送电，电网用电低谷期时，通过智能调控器控制将风力发电机组和潮汐电站切换到抽水蓄能电站的抽水机组並在涨潮海水高位时，以较小的电耗提高高位海水的势能，存储在海拔高度高于高潮位线上的抽水蓄能电站水库，待退潮时蓄能电站水库内的海水势能自然增加，此时蓄能电站放水发电可以起到增能的效果。本发明的发电系统在向电网送电的全过程中，不消耗化石能源，可以零排放获取可调节的最适合需要的电能。 
附图说明
图1为本发明的原理图。 
图2为本发明的示意图。 
图3为本发明的另一种示意图。 
具体实施方式
下面结合附图对本发明作进一步说明。 
如图2、图3所示，在海岸带或近海岛礁选择筑垻能形成封闭水域的蓄能水库，封闭水域内的海水能在潮汐作用下，在人为安排下进出封闭水域。诸如两个伸入海中的海岬之间谷地或海湾，在高、低潮位海拔高度间筑垻建潮汐电站，谷地或海湾高潮位潮位线上，筑垻建抽水蓄能电站，海岬最高处建风力发电机组，也可以在已有潮汐电站附近选择高潮位潮位线上筑垻建抽水蓄能电站，海岸高处或常年风口处建风力发电机组，这样的选择建潮汐电站和抽水蓄能电站的条件，在岩基海岸带或近海島礁带，是有很大选择余地的，作爲蓄能载体的水可以取之不尽，海岸带人类活动频繁，基础设施齐全，可以获得已有输电设施支持。图1所示本风能、潮汐能互补蓄能发电系统，包括智能控制器2、风力发电机组1、潮汐电站及机组3、抽水蓄能电站及机组4，所述的抽水蓄能电站水库坝底海拔高度高于潮汐电站坝顶海拔高度，风力发电机组经换向开关6分别与抽水蓄能电站4抽水机组或变压器5连接，潮汐电站机组3经换向开关6分别与抽水蓄能电站4抽水机组或变压器5连接，所述的智能调控器2分别与风力发电机组1、潮汐电站及机组3、抽水蓄能电站及机组4连接。 
所述的潮汐电站及机组、抽水蓄能电站及机组，为同一水系的上下两个水库电站。
所述的抽水蓄能电站机组为发电＝抽水两用可逆机组。 
所述的智能控制器2可以根据电网负荷、潮汐时海水的海拔高度，调节风力发电机组和潮汐电站机组在最佳时段向电网送电，或是抽水蓄能，达到本风能、潮汐能互补蓄能发电系统的优化，使在潮汐高潮位时以最少的电能将海水存储在抽水蓄能电站内，低潮位时获取增加的势能发电，以补电网峰电之缺口。
