| 摘 要： | 维持电网频率在规定的范围内,是水轮机调节的基本任务。本文首先介绍了调速器开度控制模式及功率闭环控制模式的控制策略,阐述了两种控制模式之间的区别,并探讨了水电机组一次调频与AGC的协联机制,分析了现有模式与改进后水电机组一次调频与AGC控制策略的要求,以某机组试验为例,验证了改进后水电机组一次调频与AGC的协联控制性能,检验了机组运行的稳定性。

| Abstract: | Maintaining the grid frequency within the specified range is the basic task of turbine regulation.This paper first introduces the control strategy of governor opening control mode and power closed-loop control mode,expounds the difference between the two control modes,and discusses the joint mechanism of hydropower unit primary frequency modulation and AGC,and analyze the requirements of existing mode and improved primary frequency modulation and AGC control strategy for hydropower units.taking a unit test as an example,the improved control performance of the hydropower unit primary frequency modulation and AGC was verified,and the stability of the unit operation was verified. |
