The invention relates to the technical field of ships and ocean engineering, in particular to a ship electric power system for reducing power configuration of a pure electric ship direct current conversion unit. The output end of the direct current busbar is connected with the input end of the first propulsion frequency converter and the input end of the second propulsion frequency converter, so that the first propulsion frequency converter and the second propulsion frequency converter have a large voltage application range. Voltage variation caused by charging and discharging of a storage battery in the storage battery system can be solved through adjustment of the first propulsion frequency converter and the second propulsion frequency converter; the boost or buck control of the first DC/DC conversion unit and the second DC/DC conversion unit can ensure the stability and availability of the input end voltage of the first daily inverter and the input end voltage of the second inverter, and also ensures the cleanness of the power grid.
本发明涉及船舶及海洋工程技术领域,特别涉及一种降低纯电船舶直流转换单元功率配置的船舶电力系统,通过将蓄电池系统与直流母排的输入端连接,直流母排的输出端分别与第一推进变频器的输入端和第二推进变频器的输入端连接,能够使得第一推进变频器和第二推进变频器有较大的电压适应范围,可以通过第一推进变频器和第二推进变频器的调节来解决因蓄电池系统中蓄电池充放电引起的电压变动;第一DC/DC转换单元和第二DC/DC转换单元的升压或降压控制能够确保第一日用逆变器的输入端电压和第二逆变器的输入端电压的稳定和可用性,同时又保证了电网的清洁。
