甘肃河西电网小干扰分析

摘要

The causes and suppression methods of low frequency oscillation in Gansu Hexi power grid are introduced, and the advantages brought by power system stabilizer are described.Small-signal analysis is carried out for the different power system stabilizer configuration in Hexi power grid.The oscillation modes of the system are studied, and the research plays some guiding roles to low frequency oscillation and its control strategy of Gansu Hexi power grid.%介绍了甘肃河西电网低频振荡的产生原因和抑制办法,阐述了配置电力系统稳定器所带来的优势,对河西电网在几种不同的电力系统稳定器配置方式下进行了小干扰分析,研究了其系统振荡模式和模态,对甘肃河西电网的振荡分析及控制策略研究有一定指导作用.
