摘要
Abstract
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,relevant recommendations are put forward.关键词
