摘　　要：针对采用传统功率调节方法易出现超调、反调等问题,尤其是在高水头工况下,笔者提出一种按“大环”“小环”“微调”分段的功率调节方法,阐述不同阶段的具体调节过程。结果表明,该方法能适应不同水头运行工况且能够满足电网调频要求。该方法可为水库容量小、水头变化大的轴流转桨式机组功率调节提供参考。Aiming at the problems of over-range control and reverse regulation in the traditional power regulation method especially under the condition of high head the author proposes a power regulation method that is segmented intolarge ringsmall ring andfine adjustment and expounds the specific regulation process in different stages.The results show that the method can adapt to different water head operation conditions and meet the requirements of power grid frequency regulation.This method can provide reference for the power regulation of axial flow with movable blade units with small reservoir capacity and large head change.
