Wind power plant primary frequency modulation control method capable of effectively utilizing kinetic energy of wind wheel

The invention discloses a wind power plant primary frequency modulation control method capable of effectively utilizing kinetic energy of a wind wheel. Aiming at the problem of poor power grid frequency modulation participation effect caused by difficulty in reasonably utilizing wind wheel kinetic energy of each unit in current wind power plant primary frequency modulation, a wind power plant primary frequency modulation power instruction is firstly designed to enable the power grid frequency to run along a set track, and meanwhile, a frequency modulation power instruction is distributed according to the maximum releasable kinetic energy proportion of each unit in the wind power plant. Secondly, the time for switching different frequency operation stages is judged by utilizing the maximum releasable kinetic energy of each unit in the field, and the key frequency modulation index, namely the maximum frequency deviation, is improved by fully utilizing the kinetic energy of the wind wheel. And finally, after the
