混合动力解决方案

  • 变频器在组合和集成方面起到重要作用  

    船舶在海上行驶和停靠港口时都需要电力推力以保持船上设备运行,98% 的船舶仍为柴油驱动。但是,由于关于氮氧化物排放的全球性法律法规越来越严,必须采用替代燃料和其它技术。 

    船舶和海工行业正寻求各种方法减少柴油消耗量和排放。趋向于使用液化天然气 (LNG) 等环保燃料。未来将使用全电动船舶。同时,造船厂和船东将加大对船舶混合动力系统的投资以提升设计和安装灵活性,优化运行性能,减少环境污染。目前,所有船舶类型,从小型短程往复运输工具到航空母舰,都可利用混合动力技术提高运行效率和环保性能。 

    显著优点有:

    • 提高船舶性能
    • 减少排放
    • 减少燃料消耗量,降低运行成本
    • 降低柴油机维护成本
    • 降低噪声等级
    • 提高供电系统的长期运行效率

    混合动力技术工作原理

    混合动力技术使用功率转换和网侧变流技术。在发电机应用以及结合使用混合负载、推进器和起重机时就用到VLT® 和 VACON® 变频器。

    采用混合动力推进的船舶使用两种或两种以上的能源: 主引擎和发电机通常与电池或超级电容器集成式储能器结合使用。首要的目的是混合能源生产以促进主引擎优化,其次是为了使所有消耗能源的机械均能利用混合能源供应以优化机器性能。

    船舶和海工行业认可使用混合动力和新型推进系统的优势。混合动力和新型推进系统可减少排放量,改善燃料消耗量,延长发动机的维护周期和使用寿命。使用混合动力推进系统甚至还可以缩小发动机规格,节约投资成本,且占用空间小。

    在能源生产中灵活性和“时间”有关。储能装置给发电留出时间,以最佳方式应对各种装载情况的变化。在加载侧,加载性能与发电无关,且“时间”不变。

    操作混合动力船舶的实际反馈和设计指标表明,将多源能源系统用于机动船可减少 20–30% 的燃料消耗量。您可以选择停止运行柴油机,使用电池或小型发电机,或断开电池或发电机后再重启发动机。

    拖船和支援船等特种船舶在长时间空转待机时主引擎仍运行,但其实并不使用任何电力进行推进。使用混合动力系统时,可通过电池和小型柴油发电机为空转待机船舶提供能量。对于在经停和固定航线行驶的渡轮,也可使用类似的方法。对于动力定位系统,可通过电池提供推进能量直到备用主引擎启动和加速,以提供长期电力推进。

    电力推进
    一般而言,船舶安装现代化电力推进系统(柴油发电、液化天然气电或全电动)的设计非常易于转化为混合动力系统。最好的情况是:仅增加一个并联储能系统就可以在用电量大时用电池供电使船舶运行。在某些情况下,最好的解决方案是以直流配电代替传统的交流配电,或混合使用。
    轴带发电机
    许多远洋船舶仍以直接柴油机推进方式运行,不使用任何电力推进系统。在推进器和主引擎之间加装一个轴带发电机可以提高这些船舶的运行效率、优化主引擎的负载功率和排放。这种系统被称为 Power Take Out (取出电源)和 Power Take In(吸收电源),是一种电动附加组件,可提高船舶的运行效率,甚至可以混合使用。在混合动力船舶中,采用交流传动技术的轴带发电机可在各种速度下优化推进装置的控制,节约能源。 
    岸电

    如果岸电系统采用变流技术,船舶可从港口当地市电网获取清洁能源。可完全关闭船舶的主发电机,防止氮氧化物和碳排放,在船舶停靠码头时防止噪音污染。

    Danfoss Drives 可提供 VLT 和 VACON 变频器、逆变器、12 脉冲低谐波系统和有源滤波器。 我们的变流产品采用 Active Front End AFE(有源前端 AFE)技术和直-直变频器以备需要使用直流功率自适应系统。网侧变流器采用 Active Front End AFE(有源前端 AFE)技术,安装可创建和控制交流电网(微电网)性能的软件。 

    储能装置/电池/超级电容器与交流电网或直流电网的接口可使用网侧变流器技术或直流变频器,这将视电网电压和电池直流电压性能和直流电压适配要求而定。
