本发明提供一种电电混合船舶直流综合电力系统及控制方法,包括包括直流母排、交流配电板、左侧发电机组、右侧发电机组、左侧锂电池组、右侧锂电池组、左侧推进变频器组、左侧作业变频器、右侧推进变频器组、右侧作业变频器;所有设备均通过直流断路器与直流母排连接。发电机组和锂电池组为直流母排提供直流电能,直流母排为推进/作业变频器和逆变器提供直流电能。直流电经推进/作业变频器转化为交流电为推进/作业电机供能,直流电经DC/AC逆变器逆变为交流电后,通过变压器输出为日用交流配电区域供能。本发明可以通过发电机组与锂电池组的不同组网和控制方式,应对船舶综合电力系统不同的运行模式,节省燃料,提高效率,降低排放。

    The invention provides an electricity-electricity hybrid ship direct-current comprehensive power system and a control method. The electricity-electricity hybrid ship direct-current comprehensive power system comprises a direct-current busbar, an alternating-current distribution board, a left-side generator set, a right-side generator set, a left-side lithium battery pack, a right-side lithium battery pack, a left-side propulsion frequency converter set, a left-side operation frequency converter, a right-side propulsion frequency converter set and a right-side operation frequency converter. All the devices are connected with the direct-current busbar through the direct-current circuit breaker. The generator set and the lithium battery pack provide direct-current electric energy for the direct-current busbar, and the direct-current busbar provides direct-current electric energy for the propulsion/operation frequency converter and the inverter. The direct current is converted into alternating current through the propulsion/operation frequency converter to supply power to the propulsion/operation motor, and after being inverted into alternating current through the DC/AC inverter, the direct current is output through the transformer to supply power to a daily alternating current distribution area. Through different networking and control modes of the generator set and the lithium battery pack, different operation modes of the ship comprehensive power system can be coped with, fuel is saved, efficiency is improved, and emission is reduced.
