The invention relates to a new energy ship hybrid battery power system and a bus protection method, a generator set is connected to a ship DC source side bus through a thyristor, a rectification controller has a short-circuit current suppression function, and a one-way suppression solid-state circuit breaker is arranged between the DC source side bus and a network side bus. The peak value and the peak value time of short-circuit current in a traditional direct-current power system are effectively reduced, and short-circuit current selective protection is achieved through the direct-current circuit breaker within 200 ms. The system can meet the zero carbon emission requirement of the hybrid battery power ship under the port entering and leaving and special working conditions, the rectification control system can quickly balance power distribution among the generator sets, various hybrid power modes are achieved through the control system, and the reliability and superiority of the hybrid battery power system are improved.

    本发明涉及一种新能源船舶混合电池动力系统及母线保护方法,发电机组通过晶闸管接入船舶直流源侧母线,整流控制器具有短路电流抑制功能,直流源侧母线和网侧母线之间设有单向抑制固态断路器,有效减少了传统直流电力系统中短路电流的峰值大小和峰值时间,在200ms内通过直流断路器实现短路电流选择性保护。该系统能够满足混合电池动力船舶在进出港和特殊工况下的零碳排放要求,整流控制系统可以快速均衡各个发电机组之间的功率分配,通过控制系统实现多种混合动力模式,提升了混合电池动力系统可靠性和优越性。
