The invention provides a cooperative control method and system for a ship self-flowing cooling system and a power system, and the method comprises the steps: collecting the navigational speed of a ship and the actual rotating speed of a propeller in the power system in real time, and obtaining the current cooling margin of the self-flowing cooling system; setting the safety margin of the minimum lifting power of the power system in the ship navigation acceleration process; according to an equal margin control strategy, obtaining the safe rotating speed of the propeller based on the current cooling margin and the safety margin; and judging the size relationship between the input reference rotating speed and the actual rotating speed difference value, and executing the corresponding safe rotating speed control state and the reference rotating speed control state or keeping the original control state. For solving the failure problem of the self-flowing cooling system in the power increasing process of a ship power system adopting a self-flowing cooling system, the cooling margin of the self-flow cooling system is defined and monitored, and an equal margin control strategy is adopted,so that the ship body navigational speed, the power system and the self-flowing cooling system can work cooperatively.
