摘要
船载中压直流电网是一个十分新颖的系统,通过中压直流电网可将交流和直流组件及系统各自的优点相结合,并结合中间的储能环节,直接通过合并各处不同的直流环节,能实现单个1 000 V的直流电路配电。可减少交流主电盘、分布式整流器和换流变压器等设备的使用,简化了舶电力配电结构,降低成本且具有高效率,简单化操作的优势。该系统可直接运用在1 000 V、20 MW的工况下船舶中。
In modern ship power system design,the shipboard DC power grid is a new system which combines different DC links of ships and directly feeds 1 000 V to them so as to reduce the number of distribution panels,the distributed rectifiers and the converter transformers. Shipboard DC power grid allows both DC and AC systems to bring their advantages to play. Also the energy management system is applied in the power grid,completely meeting the requirements and regulations on the selectivity and equipment protection.The grid can supply 20 MW 1 000 V DC power for ships.
