The installed capacity of new energy in Hebei South Power Grid is increasing

which leads to the weakening of primary frequency regulation ability of power grid.Therefore

new energy is required to have the ability to participate in primary frequency regulation of power grid.This paper analyzes three ways and their advantages and disadvantages of primary frequency regulation transformation of new energy station.For the new energy station of Hebei South power grid

the analysis and calculation of primary frequency modulation response dead zone

response amplitude limiting

frequency ending point

modulation difference rate and other parameters are carried out

which can provide technical support for the primary frequency regulation transformation and field test of new energy station.According to the parameters of this paper

the primary frequency regulation response device is configured.Through field measurement the accuracy and effectiveness of the device under frequency step disturbance are verified.
