Based on the CCS-DEH coordinated mode of the PFR,rapid and enduring PFRs can be achieved after the thermal power unit operates in the turbine-boiler coordinated way.The analysis of the results of the dynamic test of the PFR of the domestic 600MW supercritical unit has shown that the maximum frequency regulation capability of the unit can be developed as far as possible,the stability of the operation of the power grid can be improved,frequency fluctuations of the power grid can be reduced,and the anti-accident capacity of the power grid can be enhanced.%火电机组投入机炉协调方式运行后,采用CCS与DEH侧协同作用的一次调频方式,能够实现快速、持久的一次调频.通过对某国产600 MW超临界机组一次调频现场动态试验结果的分析,尽可能发掘该机组的最大调频能力,提高电网运行的稳定性,降低电网的频率波动,增强电网的抗事故能力.
