【 摘 要 】

Analysis the deficiencies of typical control strategies for AGC regulation and primary frequency regulation on conventional hydropower units. The logical relationship between primary frequency regulation and AGC is optimized. A new regulation method is proposed and applied in a hydropower plant. Practice shows that the method can avoid contradiction between AGC load adjustment and primary frequency modulation, and improve the frequency modulation performance of the unit. The optimization finally satisfy the requirements of power grid assessment.
