The invention provides a variable pitch control system for a marine energy generator set. The variable pitch control system comprises at least two parallel variable pitch control shaft boxes, a PLC system and a servo driver are installed inside each variable pitch control shaft box, and a permanent magnet synchronous motor, a proximity switch, a limit switch, a pressure sensor, a two-position rotary switch and a three-position self-reset rotary switch are installed on the exterior of each variable pitch control shaft box, wherein a normally close contact of one limit switch, one normally opencontact of the two-position rotary switch and a normally open contact of one relay controlled by the PLC system are connected in parallel to be connected to an enabling input terminal of the servo driver to serve as a drive enable signal of the servo drive. The variable pitch control system for the marine energy generator set can realize the variable pitch action of a paddle within a wide range, can effectively reduce the
