This paper introduces the basic principle and control structure of primary frequency modulation on the thermal power units, at the same time gives the forming method of primary frequency modulation compensation instruction. Combined with the actual power production and aiming at the actual problems of primary frequency modulation, this paper presents the flexible limiting control method of primary frequency modulation instruction and on-line automatic correction method, which can effectively improve the primary frequency modulation performance on the thermal power units and ensure the safe operation of power grid. This scheme provides reference for other units to improve the primary frequency modulation optimization.
