Description

安装水电涡轮发电机的方法
技术领域
本发明涉及安全地安装海底潮汐水电涡轮发电机的方法。
背景技术
环境意识的渐增关注以及不愿依赖于非可再生能源使得更大程度的利用可再生能源系统，例如，太阳能动力、风能动力、热能动力和潮汐能动力。后者涉及到涡轮发电机在潮汐流区域中的安装并且将潮汐的能量转换成电动力。
参考图1，在PCT申请No.PCT/EP2007/006258中描述了直接驱动无轴式永磁水电涡轮发电机。发电机10包括环形定子12和转子14，定子12具有围绕定子12的周缘定位的多个线圈(未示出)。转子14包括内轮圈16，内轮圈16限定开放式中心。转子14进一步包括捕获在内轮圈16和外轮圈20之间的大致径向延伸的刀片18排列。转子14进一步包括围绕外轮圈20布置的磁体排列(未示出)。定子12同心地环绕转子14，使多个线圈为磁体提供磁通返回路径。
发电机10定位在潮汐流区域中，以使得通过发电机10的海水的运动作用于刀片18上，使得转子14在定子12内旋转。磁体相对于定子12的线圈的运动使得由磁体产生的磁场在各个线圈中感应EMF。这些感应的EMF提供了从涡轮发电机10输出的电力。
为了可接受的良好惯例起见，应当理解的是，当进行高电压电气设备的安装和连接时，应当遵循某些安全规则，例如，设备应当与所有可能的供电点切断；与所有可能的供电点隔离开；通过在切换点处应用的安全扣锁进行安全保护；以及通过电路主地线接地。
尽管当处理上述海用电气设备时可以容易地坚持上述标准，与水下涡轮发电机的隔离相关的问题很大程度上来自于开关装置的不可接近性以及需要从非常远的距离(例如，从近岸电站)激励和去激励涡轮发电机。
因此，该方法专利的目的是提供用于安装和连接水电涡轮发电机的方法，所述方法提供确定性和安全性并且减少了在可能危险的条件下所需的操作。
发明概述
因此，提供安装海下潮汐水电涡轮发电机且利用水下电力电缆将所述涡轮发电机连接至供电网的方法，其中，所述水电涡轮发电机包括电气制动系统，所述电气制动系统可操作以便在控制信号中断时向所述涡轮机施加电气制动，其中，所述控制信号通过所述水下电力电缆从连接点处的控制器传送到所述供电网，所述方法包括以下步骤：
(i)将水下电力电缆放置到适当位置上，所述水下电力电缆从与供电网的连接点处的第一端延伸到期望安装海下潮汐水电涡轮发电机的安装场所处的第二端；
(ii)将所述水下电力电缆连接至所述连接点；
(iii)利用供电开关将所述水下电力电缆与所述供电网切断；
(iv)利用隔离开关将所述水下电力电缆与所述供电网隔离，将所述电力电缆接地；
(v)向所述供电开关和所述隔离开关施加安全扣锁；
(vi)通过断开控制开关来中断所述控制器处的控制信号，向所述涡轮发电机施加电气制动器；
(vii)向所述控制开关施加安全扣锁；
(viii)将所述水电涡轮发电机布置在所述安装场所处；
(ix)将所述水下电力电缆连接至所述水电涡轮发电机；
(x)从所述供电开关和所述隔离开关移除所述安全扣锁；
(xi)利用所述隔离开关将所述电力电缆与地断开；
(xii)利用所述供电开关将所述电力电缆与所述供电网接通；
(xiii)将所述安全扣锁从所述控制开关移除；以及
(xiv)闭合所述控制开关，以使得所述电气制动器从所述涡轮发电机移除，并且允许所述发电机开始发电。
由于涡轮发电机被下降到现场的适当位置上，在安全过程中涡轮机不可能开始自旋。这是因为不具有仅能够通过水下电力电缆施加的供电信号而使闩锁接触器不能够改变状态，电缆保持不连接至涡轮发电机直到已经布置发电机之后。而且，在电气制动器从涡轮机释放之前，涡轮发电机的电气制动系统需要接受控制信号。由于控制信号经由水下电力电缆传送，在电力电缆不连接至发电机的情况下，制动器不可能释放。因此，安装人员可以确保尽管布置有发电机涡轮机不开始自旋。此外，由于水下电力电缆与主供电网切断和隔离，由于电力电缆不通电，安装人员可以在安装操作过程中安全地处理电力电缆。
优选地，所述方法在步骤(ix)之前进一步包括测试所有海下电路是锁死的步骤。
从安全方面考虑重要的是，确定在布置发电机之前所有的海下电路是锁死的并且安全地切断电源，以便确保在安装过程中不存在涡轮机触电和/或移动的危险。
优选地，在所述连接点处执行步骤(ii)-(viii)和(xi)-(xvi)。
由于可以远离涡轮发电机的安装场所来执行大多数步骤，这减少了必须在近海场所执行的步骤的数量，并且相应地降低了与可变天气条件下的操作相关的危险。
优选地，所述方法进一步包括以下步骤：
(a)一旦电力电缆已经被切断和隔离，记录与所述水下电力电缆的第二端相关的位置标记；以及
(b)在步骤(ix)之前，验证涡轮机布置正在与所述特定水下电力电缆的第二端相关的所述位置标记处发生。
专用验证步骤的实现意味着涡轮发电机仅布置在正确的位置处并且确保安装操作员不将涡轮发电机连接至可能通电的水下电力电缆。
优选地，所述位置标记包括GPS坐标。
优选地，所述方法进一步包括以下步骤：
(a)在将所述水电涡轮发电机布置在所述安装场所处之前，闭合所述水电涡轮发电机上的闩锁接触器以便将所述水电涡轮发电机的正极输出端子和负极输出端子接地；以及
(b)在所述水电涡轮发电机布置在所述安装场所处之后，断开所述闩锁接触器以便将所述水电涡轮发电机的输出端子与地断开。
优选地，步骤(ix)进一步包括：将所述水电涡轮发电机布置在所述安装场所处，以使得所述涡轮机的轴线与所述安装场所处的主潮汐流的方向对准。
由于涡轮发电机与潮汐流对准，这提供了处于安装场所处的涡轮机的最优性能。
优选地，水电涡轮发电机包括用于将所述发电机连接至水下电力电缆的发电机电缆，并且其中步骤(x)进一步包括将所述水下电力电缆的第二端和所述发电机电缆回收到用于连接的安装容器，其中，所述水下电力电缆和所述发电机电缆用于将所述安装容器稳定在所述安装场所处的适当位置上。
安装的发电机的水下电力电缆和发电机电缆为安装容器提供了系泊工具，有助于将安装场所稳定在近海位置处。
还提供安装水电涡轮发电机排列的方法，包括如上所述的安装单个水电涡轮发电机的步骤，其中，所述水电涡轮发电机进一步包括用于连接至另一水电涡轮发电机的扩展电缆，以使得多个水电涡轮发电机可以菊链方式连接到一起，并且其中，所述方法进一步包括以下步骤：
(a)将连续水电涡轮发电机布置在连续安装场所处；
(b)将在前水电涡轮发电机的所述扩展电缆连接至续后水电涡轮发电机的所述发电机电缆；以及
(c)对于排列中的所述水电涡轮发电机中的每个重复步骤(a)和(b)，其中在步骤(xi)-(xvi)之前执行步骤(a)-(c)。
由于水电涡轮发电机可以菊链方式串联地连接到一起，借助于隔离、接地和锁定的整串涡轮机来执行涡轮机排列的安装。然后一起激励整个涡轮机排列。
附图说明
现在，参考附图仅通过实施例的方式来说明本发明的实施方案，其中：
图1为现有技术水电涡轮发电机的等距图；
图2为用于将水电涡轮发电机安装和连接到供电网的样本构造的轮廓；
图3为在布置在安装场所之前安装容器和水电涡轮发电机的图；以及
图4为在布置在安装场所之后安装容器和水电涡轮发电机的图。
发明详述
参考图2，呈现出用于安装水电涡轮发电机10的样本电路方案的总体视图。发电机10安装到安装场所的潮汐流区域中，发电机10设置在海底安装支撑结构22上。发电机10进一步包括发电机电缆24，发电机电缆24可操作以将发电机10和水下电力电缆连接，发电机电缆24包括用于连接至发电机10的输出端子的适当的电力线。
发电机10可以进一步包括扩展电缆26，扩展电缆26包括耦合至发电机电缆24的电力线的另一组电力线，扩展电缆26允许一系列单独的发电机10以菊链方式连接到一起，从而使一系列发电机10的输出可连接至单根水下电力电缆。
发电机10包括一组机械闩锁的两极DC接触器28，接触器28连接至发电机10的正极输出和地之间以及发电机10的负极输出和地之间。接触器28由DC控制线30控制，到DC控制线30的输入由发电机电缆24接收到。
发电机10还可以包括电气制动系统(未示出)，所述电气制动系统可操作以至少横过发电机10中的线圈的部分来施加短路，从而向涡轮机施加电气制动且防止涡轮机旋转。电气制动系统由从发电机电缆24接收到的控制信号致动，以使得如果存在控制信号供给的中断则施加电气制动。
近岸变电所通常表示为32。变电所32包括到电压源，例如供电网的连接器34。变电所还包括多个控制器36，控制器36可操作以便为发电机10产生控制信号。
变电所32连接至水下电力电缆38。电缆从变电所32处的第一点放置到期望安装发电机10的第二点。电缆38包括电力果心线以便传输由发电机10产生的电力，以及用于将来自变电所32的控制信号传送到发电机10的至少一根控制线。电力电缆38连接至变电所32。
变电所32进一步包括连接电缆38的电力线与电压源连接器34的供电开关40以及连接电缆38的电力线与地的隔离开关42。
变电所32进一步包括可操作以向控制器36提供电力的控制器电压源44，控制器电压源44经由控制器供电开关46连接至控制器36。
在为涡轮机的布置和连接做准备时，机械闩锁的接触器28设定在闭合位置上，将发电机10的正极输出端子和负极输出端子接地。该接触器的闩锁位置由用于安装操作的高级经授权电气人员(SAEP)进行测试和验证，SAEP将负责即将到来的近海电气工作。
在布置之前，供电开关40应当断开，并且隔离开关42应当闭合。该操作由SAEP作证。这两个开关布置随后由安全扣锁进行紧固，并且钥匙的所有权由SAEP保持。
在布置之前，用于控制器36的控制器供电开关46也断开并且扣锁到适当位置上。该锁的钥匙也应当由SAEP保持。
尽管SAEP处于近岸变电所，SAEP应当利用校准的电压测试装置来确保所有的海下电路是锁死的。
仅当SAEP对涡轮发电机隔离布置(通过闭合接触器28以及切断向控制器36的供电)、近岸变电所隔离(通过断开供电开关40以及闭合隔离开关42)满意并且具有安全扣锁的所有钥匙的所有权时，近海操作才能够开始。一旦SAEP对上述情况满意，需要SAEP对启动发出许可。
在启动之前，SAEP记录与水下电力电缆38的刚刚切断供电且隔离的末端有关的位置信息。
参考图3，一旦到达安装场所52，SAEP负责验证安装容器50的GPS坐标与上述隔离的特定电缆末端的记录位置的坐标一致。一旦已进行验证，可以开始涡轮发电机10在安装场所52的布置。
涡轮发电机10布置有处于闭合位置的机械闩锁接触器28。由于水下电力电缆38未连接的事实，在得知涡轮发电机10在布置期间不可能开始自旋的知识后，SAEP和工作团队可以是安全的，因此，接触器28不可能改变状态或者电气制动器不可能释放。这起到了与近岸扣锁类似的作用。
参考图4，发电机10和支撑结构22借助于如图3所示的发电机电缆24和在来自于涡轮机布置容器50的甲板的张力下铺设的扩展电缆26下降到海底54。一旦涡轮发电机10定位在海底54，容器50开始铺设两个电缆尾端24、26。电缆24、26的末端布置有块重量(未示出)。由于在不供电情况下闩锁的接触器28不可能改变位置或者电气制动系统不可能分离，可以处理电缆的末端，而不具有末端变成通电的危险。供电不可用，直到电缆38完全连接至发电机电缆24且解锁返回到近岸变电所32处。接触器28还将发电机电缆24(因此扩展电缆26)连接至局部接地点，因此电缆24、26安全地接地。
水下电力电缆38的末端和发电机电缆24的末端随后可以恢复到电缆安装容器50的甲板并且接合以将发电机电缆24连接至近岸变电所32。由于发电机电缆24不可能通电直到电缆接合已经完成，在该接合过程中发电机电缆24是安全的以便进行处理。由如下事实提供进一步的确保：向水下电力电缆38的供电扣锁在断开位置上(供电开关40)，并且该锁的钥匙由负责电缆连接的SAEP所有。
由于涡轮发电机的轴线与电流对准，在电缆接合操作期间容器50将与电流对准，使双芯电缆悬链线从容器50的艏柱延展出。发电机电缆24及其到潮汐涡轮支撑结构22的附接件将具有足有的强度以使得其可用于提供大的系泊力。不超过电缆上最大容许张力，发电机电缆30和水下电力电缆24的两根电缆悬链线将提供基准和稳定效果以便辅助当在高能潮汐场所实施接合操作时通常为高风险因素的容器定位。
一旦电缆接合完成，两根电缆38、24的末端将下降到海底54。
现在完成了近海操作。涡轮发电机10现在可以执行任务且与近岸变电所32通电。SAEP返回到近岸变电所32，并且所有的安全扣锁被移除。
隔离开关42断开，将电力电缆38与地断开。供电开关40闭合，将电力电缆38连接至负载。控制器供电开关46接通。现在可以利用适当的控制器36来释放海下机械闩锁的接触器28。一旦海下开关28的状态改变，电气制动器被释放，并且可以开始发电。
通过使用接触器28的控制线圈上的接地回流电路，每个涡轮发电机10仅需要一根控制线。注意的是，在水下电力电缆38中存在有限数量的控制线，且因此存在能够装配到单根水下电力电缆38上的有限数量的涡轮发电机10。通过使用用于控制的接地回流电路，有效地将能够由单根电力电缆38控制的涡轮发电机10的数量加倍。而且，由于大的支撑结构22沉浸在海水中导致接地回流电路的电阻非常小，因此电压降减半。控制电流的连续流动可导致随时间的腐蚀或导航干扰。使用闩锁接触器28意味着控制信号可通过接地而跳动，并且因此对于腐蚀或环境没有影响。
可以利用如上文详述的相同的方法在以后将第二个涡轮机增加到排列中。在可以增加第二个涡轮机之前，整个涡轮机串需要进行隔离、接地和锁定。然后一起激励整串涡轮机。
