摘要
分析了电力系统中低频振荡的产生原因及数学定义,并提出了改善系统阻尼的措施,重点研究了PSS对低频振荡的抑制作用,以有效提供正阻尼,抑制电网低频振荡,保证电网的动态稳定性。
The paper analyzes the reasons for the low-frequency vibration in power system and the definition of digits,points out the measures for improving system damping,and researches mainly the restraining role of PSS on low-frequency vibration,so as to provide the damping effectively,to restrain the low-frequency vibration of grid,and to ensure the dynamic stability of grid.
