Ship hybrid power system and control method

The invention discloses a ship hybrid power system and a control method, the system can meet the rapid dynamic response of a ship and also can realize long-distance sailing, and the coupling mode between the two sets of power systems can gain each other: an electric power system enables a diesel oil system to rapidly increase the rotating speed; the diesel system supplements energy to the electric power system. Coupling a power system and a diesel system and controlling the system; the SSPC cuts off power output in time when a single cluster of batteries go wrong, and power is supplemented through a diesel system at any time; through coupling and system control of the diesel oil system and the electric power system, the power system can realize economical and efficient operation in various ship use scenes; the hybrid power high-voltage system can be monitored in real time in the whole life cycle, and the service condition of the battery is monitored in the whole life cycle through AFE sampling; normal use of
