Description
技术领域
本发明涉及一种控制风能设备(wind power installation)的方法,以及尤其用于执行该方法的风能设备。
背景技术
风能设备长期以来是普遍公知的,近来作为有利环境的能量发生器越来越多地得到使用。
从道理上说风能设备暴露于天气的影响之中。对于风能设备具有较大影响的一个问题是湿气,带有电系统的风能设备必须受到较大程度的保护以防止湿气。
但是,这种设备不能被密闭地封闭来可靠地避免湿气的侵袭,因此通过附加的封装装置如机壳使得湿气必须远离设备的某些部件。但是,这种封装装置是不可行的,特别是在风能设备吊舱(pod)的具有较大金属质量体如发电机的区域中。
但是另一方面,正是该较大质量体还导致了主要问题,例如,如果较大质量体一夜之间冷却,那么设备周围区域的温度升高。
由于暖空气会比冷空气存储更多湿气,因此当设备处于停止状态时,富含湿气的暖空气也流入吊舱(pod),在此与仍然为冷的发电机相遇。接着,湿气沉积到发电机上,冷凝形成水,水量可能很大。
对于包括环形发电机(ring generator)的风能设备来说这是一个特殊的问题,其中水进入发电机,然后在发电机启动时,即其被提供激励能时,会导致相当大的损害。
发明内容
因此,本发明的目的是消除因为水造成的这种危险。
该目的通过在本说明书开头部分阐述的那种方法实现,所述方法包括如下步骤:
a)检测发电机的温度、以及风能设备周围的空气温度;
b)确定温差;以及
c)如果发电机的温度低于周围空气(ambient air)的温度,则加热发电机。
此外,该目的通过本说明书开头部分阐述的那种风能设备来实现,该风能设备包括:用于定子短路的装置;具有至少两个温度拾取器用于感测发电机温度和周围空气温度的控制器;以及用于比较温度的装置,以使控制器可以根据温差使发电机的定子短路,并可以以预定的激励电流(excitercurrent)作用于转子。
对于上述结构可以替换或者补充的是,还可以在风能设备的吊舱中,例如在发电机的一些部件上或者其他电敏感部件(electrically sensitive part)上,设置湿气和/或冷凝物传感器作为检测发生在该处的湿气或冷凝物的装置,且传感器检测到的值在控制装置中进行处理,如果测量到的湿气和/或冷凝物的值高于预定值,则进行具有本申请描述的装置的发电机的加热或者风能设备其他部件的加热。
附图说明
在下文将参照附图更加详细地描述本发明,附图中:
图1是发电机定子和转子的简化视图;以及
图2还示出了另一个实施例中的发电机的定子和转子。
具体实施方式
图1是示出包括定子10和转子12的发电机的较为简化的视图。定子10具有连接端子,在正常操作中在该端子处可以将电能引出(take off)。转子12也具有连接端子,借助该连接端子提供激励电流。
定子10的连接端子之间示出的是被控制装置20致动并且使定子连接短路的触头。
控制装置20借助两个温度传感器22、24检测发电机的温度(此情况中是定子)以及风能设备周围的温度。
如果传感器22检测到的定子温度低于传感器24检测到的环境温度,则定子的连接端子之间的触头关闭,由此形成短路。
接着,借助转子12的连接端子,将预定的激励电流输入定子12中。发电机定子中感应的功率会受到输入到转子12中的激励电流大小的影响。
当定子短路时,定子电压极低,这种情况下极高的电流(短路电流)流过,其导致相应的焦耳热(joulean heat)在定子中产生。发电机通常由该焦耳热加热,使得湿气蒸发。因而,通过本发明,借助包括测量技术的监控装置,即使是冷凝水的形成也在此优化的发电机中得到记录,这种情况下,(处于启动模式下的)风能设备在非常低的电压的加热模式下自动启动,该模式导致发电机中的残余湿气蒸发。从而侵入风能设备的吊舱中的湿气尽可能地少,整个吊舱机壳为水密构造,从而导电物质如湿气的入侵被(吊舱上的)外覆层防止。
在本发明的优选改进中,在风能设备变化到正常模式之前,也即,在消除定子短路以及正常激励能输入到装置中之前,持续发电机的加热,直到发电机温度超过周围空气温度一预定量为止。
图2示出了包括定子10和转子12的发电机的另一个实施例。
该实施例中,加热电阻器14设置在定子10和转子12上,加热电阻器14围绕周边均匀分布。如果控制器(未示出)20检测到发电机定子10和周围空气之间的温差,则接通加热电阻器14,因此发电机被加热。发电机中的湿气蒸发,且在预定时间之后或者当定子10和转子12的温度与周围空气之间达到预定温差时,可以采纳正常操作。
不仅对于发电机,而且对于风能设备内部的其他电敏感部件都可以设置特殊的加热装置。这种加热装置如同发电机加热一样受到有规律地控制,也即,当将被加热的部件的温度低于外界环境温度时,进行加热,从而防止了湿气在该电部件上的沉积。
最后,对于发电机或周围空气的温度检测可行的、可替换的或者可补充的是,提供一个(或多个)湿气/冷凝物传感器,该传感器设置在发电机(或其他敏感部件上)并且检测沉积在发电机上的湿气和/或冷凝物,如果传感器连接到控制装置上,则如果传感器测量到的冷凝物超过设定值,发电机的加热便自动启动。
最后,还提出,如果湿气沉积物形成在发电机上或其他电敏感部件上的问题较频繁地发生,则进一步设置蒸发促进装置。为了促进发电机或其他电敏感部件的快速干燥,还可以提供送风机,其如同吹风器一样工作并将热空气传送到要被干燥的各个部件上。因此,例如通常设置在任何风能设备中用于提供新鲜空气的送风机也可以设置在加热装置的下游,使得所提供的新鲜空气在灼热状态下转向到发电机吊舱内部,因此防止了潮湿的空气沉积在例如发电机的电敏感部件上。
本申请的发明还包括以任何可想象的方式检测形成在风能设备的发电机上或其他电部件上的湿气(湿气沉积物)。这也可以通过在特殊敏感区域中测量电流是否在该处表面上发生而实现,该电流只可能在湿气沉积物已经形成时发生。
