The invention belongs to the technical field of satellite-borne load application, and particularly relates to a satellite-borne large-inertia rotating load angular momentum and moment compensation method and system. The problem that an existing compensation mode cannot meet the large-inertia high-rotating-speed load compensation requirement is solved. The system comprises a first speed conversionunit, a balance wheel system, a second speed conversion unit and a rotary table system. The process of the method is as follows: firstly, an expected rotating speed given by a satellite is converted into a target rotating speed of a balance wheel; a balance wheel starts to accelerate to the target rotating speed; the rotating speed of the balance wheel is calculated in real time through Hall signals output by the balance wheel, the real-time rotating speed of the balance wheel is converted into the given rotating speed of the rotary table and rotates reversely, and therefore it is guaranteed that the rotating speed of the rotary table is matched and tracked with the rotating speed of the balance wheel in the acceleration process, the constant speed process and the deceleration process in real time, and the residual angular momentum and residual torque compensation effect is guaranteed.
