The invention relates to the technical field of frequency modulation control, and discloses a primary frequency modulation control system for a small-disturbance thermal power generating unit. A primary frequency regulation paramete control model of that self-adaptive small-disturbance thermal power unit is construct; The parameter control model of the primary frequency regulation of the self-adaptive small disturbance thermal power unit is optimized and solved; The frequency disturbance of the power system is detected, and the frequency modulation control is carried out on the thermal power unit according to the current frequency modulation parameters of the thermal power unit. The invention realizes the detection of the frequency disturbance of the power system and the correction of the frequency of the power system after the disturbance occurs.
