A ship high-power electric propulsion virtual synchronous motor control method includes the steps that a ship high-power electric propulsion virtual synchronous motor model is built, virtual synchronous motor control is adopted for a rectification part of the ship high-power electric propulsion virtual synchronous motor model, and power grid alternating-current power fluctuation is restrained by simulating inertia characteristics of a motor rotor; vector control is adopted for the inversion part of the active front-end converter, efficient control over the propulsion device is guaranteed, and therefore virtual inertia characteristics are added to the system, the control capacity of the active front-end converter is fully exerted, and alternating-current power impact is restrained on the premise of not depending on an additional energy storage device and not losing speed regulation performance. 一种船舶大功率电力推进虚拟同步电动机控制方法，通过构建船舶大功率电力推进虚拟同步电动机模型，对其整流部分采用虚拟同步电机控制，通过模拟电机转子的惯量特征，抑制电网交流功率波动；对其逆变部分采用矢量控制，保证推进装置的高效控制，从而为系
