The invention provides a direct-current constant-voltage power generation system of a novel extended-range generator set. The direct-current constant-voltage power generation system comprises a permanent magnet synchronous generator set; the permanent magnet synchronous generator set comprises an engine, a permanent magnet synchronous generator, a generator controller and a generator set controller. Wherein the engine is used for working in a rotating speed control mode and adjusting the working rotating speed according to a rotating speed control instruction issued by the generator set controller; the permanent magnet synchronous generator is used for working in a magnetic field equivalent current control mode and is coaxially connected with the engine, and the engine drives the permanent magnet synchronous generator to rotate; the generator controller is used for converting the three-phase current of the generator into two components of a magnetic field equivalent current and a torque equivalent current through coordinate conversion by adopting a vector control strategy; and in the direct-current constant-voltage power generation mode, the equivalent current of the magnetic field is controlled, and alternating current generated by the permanent magnet synchronous generator is converted into expected direct-current voltage. The problem that the battery cannot be separated to work independently in a power control mode is solved.
