摘要
以水火电三机联合系统为例,提出了多机系统的低频振荡研究模型,综合考虑了励磁调节系统、汽轮机调速系统和水轮机及其调速系统的作用,对不同状态下的特征根进行了比较,并做了振荡模式的相关性和灵敏度分析,结果表明了水轮机及其调速系统对电力系统低频振荡模式的影响不可忽略.
In the conventional model for the analysis of power system low-frequency oscillation, excitation systems are considered as the main components that cause the low-frequency oscillation; hydro turbine and governor system are usually ignored, In this paper, a low-frequency oscillation model considering hydro turbine and speed governor is proposed, The results obtained by using eigenvalue relativity and sensitivity analysis method show that the hydro turbine and governor system have influence on the power system low-frequency oscillation mode.
