混合渡轮连接阿姆斯特丹市不间断

在阿姆斯特丹的IJ河上,由Vacon®驱动器提供动力的混合渡轮享受24/7正常运行时间,较小的发电机尺寸,改善的空气质量,更少的噪音和易于操作性。

GVB具有将其渡轮,电车,公共汽车和汽车的排放和环境影响减少到绝对最低限度的政策。因此,当GVB从荷兰造船厂订购2辆新渡轮时,他们决定使用电池混合动力技术来提高燃油效率并降低污染。

峰值降低发电机的大小
渡轮每年24小时365天操作。穿过IJ河大约需要4分钟,然后将渡轮停靠约2分钟,然后再出发。

由于在港口停靠的时间太短,无法从海岸电源连接中为电池充电,因此无法使用100%电池供电的电渡轮。取而代之的是,GVB决定使用带柴油发电机和锂离子电池的电推力来刮去电源峰。

这使他们能够缩小发电机的尺寸,因为这些电池使发电机能够以几乎恒定的负载非常有效地运行。

混合动力改善了空气质量…
为了减少剩余的空气污染,柴油发动机配备了有效的排气清洁系统,也称为SCR(选择性催化反应器),可去除有毒的气体和颗粒。

IJ Ferries 60和61已经符合新的更严格的空气污染规则,该规则将于2019/2020起适用。这有助于提高空气质量并减少阿姆斯特丹公民以及使用渡轮的数百万游客的噪音。

…和机动性
船长对新渡轮感到非常满意:渡轮与传统柴油动力的姊妹船一样容易处理,但它们安静得多。低噪音水平使乘客和机组人员都感到愉悦。

24/7正常运行时间
阿姆斯特丹市认为渡轮是“漂浮的桥梁”,这有助于将阿姆斯特丹渡轮的北部和南部绑起来。出于安全原因,选择了两个冗余的直流网格系统 - 但短路保护是一个挑战。GVB对该解决方案感到满意,下次需要新渡轮时,将考虑相同的混合船。
