变革性的技术
岸电技术的核心在于变频电源系统,即将岸上工频50Hz转变为船用60Hz,并在转换过程中实现同步无缝切换。目前国内现有码头船用供电系统涉及变频技术的案例并不多,有很多都是直接变压而不变频的岸电技术,相当于低压交流充电桩,无法做到不间断供电。
西门子不仅具有的变频技术,对船用电气技术也有深入的理解,其岸电的变频电源系统采用Sinamics S120 系列针对变频电源应用的变频模块作为岸基供电系统的核心,整体系统具备四象限整流单元(IGBT)、短路故障穿越、结构模块化易于扩展、开放性系统以及并网同步切换等特点,很好地起到了稳压、稳频,以及谐波抑制的作用。
基于这一核心技术,西门子能够为岸电变频电源系统提供完备的从咨询、设计到制造执行等的整体解决方案,可根据用户需求设定 440V/60Hz,6.6kV/60Hz,400V/50Hz,6kV/50Hz 等多种制式电源上船的全方位岸电系统,适用于散货码头、集装箱码头以及大型邮轮码头。
