The frequency security and stability situation in low load mode is worsening. The key factors which affect the frequency response are analyzed from the point of view of the load model
turbine-governors and drum boiler in the “9·19” incident. On the basis of measured values
the load frequency factor
the parameters of primary frequency modulation limit
frequency coefficient
and main steam pressure are identified. The results reflect the dynamic frequency trajectory of the “9·19” incident successfully. According to the results of reconstitution
