Cause analysis and preventive measures of abnormal regulation of AGC in a power plant

Abstract

Abstract:

There is abnormal load regulation of AGC due to the disparity between power plant side and dispatching side parameter.Through the AGC data transmission, command algorithm, numerical conversion and adjustment mode analysis, the cause of abnormal load regulation is confirmed.Briefing from safety technical measures, parameter setting, command verification, test verification and process management ,specific preventive measures are proposed for AGC parameter adjustments that could lead to abnormal load regulation.It could provide reference for adjustment of AGC abnormal regulation and operation maintenance.
