Self-sustaining system of deepwater photovoltaic mobile platform

A self-sustaining system of a deepwater photovoltaic mobile platform comprises a plurality of grid control points, a tension sensor, a grid outline thick cable, an ocean current meter, floaters and a photovoltaic small grid. The grid control points and the grid rope thick cables are fixed to form a grid rope, and the photovoltaic small grids are distributed in the grid rope in a net shape through thin ropes; the floaters are arranged on the thick cables and the thin ropes of the grid rope; the ocean current meter is connected with the grid line thick cable; the tension sensor is arranged on the thick cable of the grid line; each grid control point comprises a control point command system, a floating platform, a power device, a Beidou receiver and a photosensitive sensor; the power device comprises two sets of power systems which are perpendicular to each other in x and y directions; the control point command system is used for receiving signals of the tension sensor, the photosensitive sensor and the Beidou r
