Discussion on Dynamic Characteristic Specification of Primary Frequency Regulation for Hydropower Unit

In order to raise the standard of primary frequency regulation for hydropower unit,the paper discusses specification of primary frequency regulation for hydropower unit by taking operation and management regulations for primary frequency regulation in Guangdong power grid as an example.On the basis of the practice,the paper points out the shortages of existing theories in responding to targeted calculation formulas and it recommends specific calculation formulas regarding control modes of speed regulator and types of artificial speed deadband;The paper analyzes effect of output response index on evaluating dynamic characteristic specification of primary frequency regulation of speed regulators under opening control mode,and it indicates that dynamic characteristic specification of primary frequency regulation for speed regulators should be evaluated in light of time of retardation,rise and stabilization.Moreover,dynamic characteristic specification of primary frequency of units seriously affected by waterpower is suggested to be optimized under opening control mode.
