Analysis and Suggestion on Unqualified Primary Frequency Regulation Action of Hydropower Unit Under the Condition of Large Frequency Difference Disturbance in Power Grid
Analysis and Suggestion on Unqualified Primary Frequency Regulation Action of Hydropower Unit Under the Condition of Large Frequency Difference Disturbance in Power Grid
A study was conducted on two 2023 hydropower units whose primary frequency modulation(FFM)operations were not up to standard during 2022 and three times of large frequency difference disturbances in Qinghai power grid,at the same time,the data of the first FM test and the qualified data of the 2024 operation of the unqualified units were analyzed to find out the reasons for the unqualified first FM operation of the units during the first three large frequency difference disturbances,at the same time,some suggestions are put forward for the following frequency modulation test and the evaluation method.
