The invention discloses a propulsion motor speed regulation control method for a ship power switching system, and relates to the technical field of motor control, and the propulsion motor speed regulation control method comprises the following steps: integrating solar power generation, wind power generation and hydroelectric generation to form a comprehensive clean energy supply unit; an operator monitors the state of the propulsion motor through a user interface; stepless speed regulation of the propulsion motor is realized by adjusting a power supply and voltage when the propulsion motor works; closed-loop control is carried out by adopting current and speed feedback; safe and reliable operation of speed regulation control of the propulsion motor is ensured through the safety protection unit; the temperature of the propulsion motor is maintained in a safe range through the cooling protection unit; when the ship needs to decelerate or stop, regenerative braking and energy consumption braking are combined to achieve energy recovery. Solar power generation, wind power generation and hydraulic power generation are integrated to form a comprehensive clean energy supply unit, and the proportion of various energy sources can be flexibly adjusted according to actual conditions so as to ensure stable operation of the propulsion motor.
