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.
