技术领域
本发明属于近海浪潮互补发电领域,涉及一种风浪潮互补发电布置方案。
背景技术
在近海领域,现代的主要的发电装置为风力发电机,在这样的海域中放置风力发电机能够有效的利用海水水域的空旷的风力,通过风力发电机产生的电能,给在近海作业的无人机和无人船提供必要的电能,减少从岸上接入电源造成的成本过高问题。
从已有的发明专利中了解到,现有的风力发电机的发电组合方式比较单一,布置简单,主要涉及的内容是提高单个发电机的效率。基于这样的情况发现风电场的海水发电空间利用率低,风力发电机的发电不均匀,以及在风浪恶劣条件下容易已损坏导致在布置的过程中造成作业和维护的成本高的问题。
发明内容
本发明方案解决的技术问题是:克服现有的发电装置组合方式单一、布置方式无须排布、海水风电场海域空间利用率低的问题,海上装备在恶劣海况下稳定性差的问题,风力发电不均匀的问题,降低发电成本,提高单位空间利用率、系统稳定性和电能传输效率。
本发明的技术方案是:一种风浪潮综合互补发电集成布置方案,包括风力发电系统、摇荡式发电系统、潮汐能发电系统和微弹系泊绳,以这种组合方式向周围进行蛛网式扩展形成蛛网式布置结构。
具体地,所述风力发电系统包括风力发电机桩柱,所述摇荡式发电系统包括均匀布置在风力发电机桩柱周围的多个摇荡式发电装置,靠近所述风力发电机桩柱的摇荡式发电装置与所述风力发电机桩柱之间、相邻摇荡式发电装置之间均分别通过微弹系泊绳绷直连接,形成蛛网式布置结构。本发明方案主要作用于近海领域,有效的解决了风电场海域发电形式单一、空间电能利用率低、抗风浪能力差以及系泊配置重复的问题,大大提高了系统在风浪条件下的稳定性和整体的电能传输效率。
进一步地,一种风浪潮综合互补发电集成布置方案,将包括以风力发电系统、摇荡式发电系统、潮汐能发电系统和系泊绳的组合方式作为一个单元,通过微弹系泊绳向四周拓展,形成多单元蛛网式布置结构。通过向四周拓展方式提高近海海域空间利用率。
进一步地,所述微弹系泊绳包括专用系泊绳和普通系泊绳,优选地,所述专用系泊绳由外侧的系泊钢缆和电缆组成,所述系泊钢缆以缠绕的方式缠绕在电线上构成专用系泊绳,电线通过系泊钢缆中间到达风力发电机桩柱下部的混合储能装置。一方面特制系泊绳通过缠绕方式保证拥有一定的轻微弹性,其次保护了内置电缆免受海洋环境影响。
优选地,所述普通系泊绳由外侧的系泊钢缆和钢丝绳芯组成,所述系泊钢缆以缠绕的方式缠绕在钢丝绳芯上构成普通系泊绳,用于与摇荡式发电系统与海桩的固定连接。特制系泊绳通过缠绕方式保证拥有一定的轻微弹性。
优选地,蛛网式布置结构整体的最外层摇荡式发电装置向外通过普通系泊绳与第一海桩绷直连接。
具体地,所述风力发电机桩柱采用海底打桩的方式固定在海底,靠近所述风力发电机桩柱的摇荡式发电装置与所述风力发电机桩柱之间、相邻摇荡式发电装置在蛛网经线上采用专用系泊绳绷直连接,内置电缆在靠近专用系泊绳头部地方从旁边引出,通过多层防水防腐蚀绝缘套保护引入风力发电机桩柱、摇荡式发电装置内部;相邻摇荡式发电装置在蛛网纬线上设置第二海桩并通过普通系泊绳绷直连接。通过在结点处打桩,最大程度将恶劣海况下的风浪集中载荷分散,提高了系统的稳定性和生存能力。多个摇荡式发电装置共用同一个风力发电机桩柱,纬线相邻摇荡式发电装置之间共用一个打桩点(海桩),减少配置重复问题。
优选地,相邻摇荡式发电装置之间的间距与摇荡式发电装置直径比为4:1。
优选地,所述风力发电系统下部设置混合储能装置,所述风力发电系统、摇荡式发电系统、潮汐能发电系统分别与混合储能装置电连接,通过混合储能装置进行初步电能逆变整合。本发明的所述混合储能装置布置在中心的风力发电机桩柱上,能够将每个蛛网单元的电能进行初步逆变整合,并传送至混合储能装置,每个单元的电能通过海底电缆传输至岸上变电站,通过向对称中心传输的方式提高了电能传输效率。
优选地,所述微弹系泊绳与摇荡式发电装置/海桩之间均通过连接环与环扣连接摇荡式发电装置。这种方式可简化连接过程,提高系统稳定性。

具体实施方式
下面将结合本发明中的附图,对本发明的技术方案进行清楚、完整地描述,显然,所描述的具体内容仅仅是本发明一部分实施方式,而不是全部的实施方式。基于本发明中的实施方式,本领域普通技术人员在没有做出创造性劳动条件下所获得的所有其它实施方式,都属于本发明保护的范围。
一种风浪潮综合互补发电集成布置方案,包括风力发电系统1、摇荡式发电系统2、潮汐能发电系统3和微弹系泊绳,以这种组合方式向周围进行蛛网式扩展形成蛛网式布置结构。本发明的蛛网布置结构根据目标海域风力发电机的功率,尺寸,间距等条件去布局,由于波浪能发电装置(摇荡式发电装置)的尺寸要远小于风力发电机的尺寸和间距,因此摇荡式发电系统可根据间距情况向外多层延展,使其布置紧凑,稳定性强。每个蛛网单元单元的层数可根据实际情况调整,每个中心风力发电机周围布置的波浪能发电装置个数也是可根据实际海域,风机情况进行适配,符合蛛网式结构即可提高稳定性。
具体地,所述微弹系泊绳包括专用系泊绳4和普通系泊绳5,如图6所示,所述专用系泊绳4由外侧的系泊钢缆4-1和电缆4-2组成,所述系泊钢缆4-1以缠绕的方式缠绕在电缆4-2上构成专用系泊绳4。电缆通过系泊钢缆中间到达风力发电系统下部的混合储能装置1-2。如图7所示,所述普通系泊绳5由外侧的系泊钢缆5-1和钢丝绳芯5-2组成,所述系泊钢缆5-1以缠绕的方式缠绕在钢丝绳芯5-2上构成普通系泊绳5,用于与摇荡式发电系统2与海桩的固定连接。
实施例1
以一个单元六边蛛网布置方案为例:
如图2-5所示,一种风浪潮综合互补发电集成布置方案,通过风力发电系统1、摇荡式发电系统2、潮汐能发电系统3和微弹系泊绳组成一个扩展网络单元,以蛛网式的扩展方式向四周延伸,构成蛛网式布置结构。风力发电机1-3产生的电流通过风力发电机桩柱1-1内部直接传送至混合储能装置1-2内。风力发电机桩柱1-1通过采用海底打桩方式固定在海底,混合储能系统1-2布置在风力发电机桩柱1-1上,并能够进行初步逆变整合。风力发电机桩柱1-1底部安装有潮汐能发电系统3,所述潮汐能发电系统3包括四台水轮机3-1和专用系泊绳4,均通过专用系泊绳4内的电缆4-2接入混合储能装置1-2。
所述摇荡式发电系统2包括均匀布置在风力发电机桩柱1-1周围水面部分的三层摇荡式发电装置2-1,多个摇荡式发电装置2-1通过微弹系泊绳共用一个风力发电机桩柱1-1。内层的六个摇荡式发电装置2-1与所述风力发电机桩柱1-1之间分别通过专用系泊绳4绷直连接,两两相邻摇荡式发电装置2-1在蛛网经线上通过专用系泊绳4绷直连接;在蛛网纬线上相邻摇荡式发电装置2-1通过普通系泊绳5系在一个第二海桩2-2上,共用一个系泊点,以此构成蛛网式布置结构,蛛网式布置结构的最外层摇荡式发电装置2-1向外通过普通系泊绳5与第一海桩6绷直连接。每台摇荡式发电装置2-1分别通过专用系泊绳4将产生的电流传送至混合储能装置1-2内。
所述摇荡式发电装置2-1包括外部壳体,壳体内设有摆锤以及与摆锤相连接的传动机构,将摆锤的动能转化成电能。所述摇荡式发电装置2-1底部连接系泊绳,属于点束缚,而系泊绳具有一定弹性,因此波浪作用下摇荡式会发生倾倒,从而摆锤转动,而本发明将系泊绳绷直有助于倾倒摇荡式发电装置2-1使其做功。
蛛网每层的间距可以根据摇荡式发电装置2-1的尺寸、活动半径匹配,在大浪情况下,摇荡式发电装置2-1因采用有微弹性的系泊绳,会前后左右运动,缓冲恶劣情况的波浪力,因此需要给摇荡式发电装置2-1之间留有一定距离,即活动半径。活动半径至少是摇荡式发电装置2-1直径的2倍,也即蛛网每层之间的间距与波浪能发电装置直径之比在4:1左右为最优比例,可以保证不会互相干涉,其次节约材料。
所述混合发电装置1-2都能够将来自风力发电系统1、摇荡式发电系统2、潮汐能发电系统3的这三种电流进行初步逆变整合,整合后的电流,再通过一条专用系泊绳4经海底电缆传输至岸上变电站,利用这种方案可大大提高了系统电能传输效率,供给来往的无人船和无人机电能,进行近海海域的勘测作业。
作为本发明优选的一种实施方式,如图9所示,弹性系泊绳与摇荡式发电装置2-1均通过连接环4-3与第一环扣2-4连接,当弹性系泊绳为专用系泊绳时,内置电缆4-2在靠近专用系泊绳4头部地方从旁边引出,通过多层防水防腐蚀绝缘套2-5保护引入摇荡式发电装置2-1内部。
作为本发明优选的一种实施方式,如图11所示,普通系泊绳5与第一海桩6、第二海桩2-2采用连接环4-3与第二环扣2-3进行连接,第二环扣2-3在打桩过程中预埋。采用这种连接方式可以简化连接过程,提高系统稳定性。普通系泊绳5处于绷直状态,形成蛛网式布置结构。
作为本发明优选的一种实施方式,如图10所示,专用系泊绳4与风力发电机桩柱1-1采用连接环4-3与套环1-4进行连接,风力发电机桩柱1-1与套环1-4直接套在一起,套环1-4上有对应环孔1-4-1,内置电缆4-2在靠近系泊绳4头部地方从旁边引出,通过多层防水防腐蚀绝缘套2-5保护引入风力发电机桩柱1-1内部。这样的连接方式可以保护电缆,另外六个方向分散受力,减少风力发电机桩的负载,而且套环直接套在桩上,不会破坏电机桩柱的结构。
实施例2
以多个单元向四周拓展构成多单元蛛网布置整体结构为例:
如图1所示,以实施例1的组合方式作为一个蛛网单元,通过微弹系泊绳向四周拓展,形成多蛛网式发电集成结构,蛛网式布置结构整体的最外层摇荡式发电装置2-1向外通过微弹系泊绳与第一海桩6绷直连接。每一个混合发电装置1-2都能够将三种来源的电流进行初步逆变整合,整合后的电流,再通过一条专用系泊绳4,直接通往蛛网中心处的风力发电系统1,将电能统一逆变整合,然后各个单元汇流的电能经海底电缆传输至岸上变电站。也可以每个单元进行拓展,电能以每个单元单独汇流,输送至岸上变电站。利用这两种方案均可大大提高系统电能传输效率,供给来往的无人船和无人机电能,进行近海海域的勘测作业。
本发明中蛛网式结构受力特点分析,如图8所示:蛛网式机构的主要特性是吸收激烈的动能,将集中载荷分散到各个结点的海桩2-2上,以维持系统结构的稳定性和各装置的安全性。由于网状结构受力分析较困难,为了简化问题,选取放射系泊绳和结点处的桩柱为简化蛛网模型,在结点处施加载荷进行静力分析。假设系泊绳材料为碳素结构钢为例,在结点处施加500Mpa单位载荷,通过有限元分析的结果,可以看到材料变形量很小,其承受的最大应力远大于材料本身的抗拉强度。因此蛛网型布置方案可以大大分散集中载荷,提高系统稳定性。
在此需要说明的是,本发明结点处可以不采用海桩的形式,采用锚链固定在海床上也可,但仍要以该蛛网式方案布置,只是将结点处的桩柱取消,换成锚链锚接点,上述方案也属于本方案的范畴。
本发明说明书中未作详细描写的内容属于本领域技术人员的公知技术。
尽管已经示出和描述了本发明的实施方式,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施方式进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
