Abstract:

The influence of primary frequency modulation on grid frequency characteristic is closely related to main technical indexes and parameter setting values of the primary frequency modulation system． Through the theoretical research，the influence degree and trends caused by different technical indexes and parameter setting values are discussed． Then，the simulation analysis and calculation are carried out on a reasonable simulation system within the large grid which is in operation． The simulation results give some measures and proposal which is beneficial to the improvement of the frequency stability．
