摘要
分析了甘肃陇南碧成系统低频振荡的原因,用特征值分析法计算了各发电机的参与因子和模态分布图,对碧口水电厂机组的PSS参数进行了整定计算,并在现场进行了系统低频振荡试验,验证了PSS对于抑制系统低频振荡的作用。
The cause of low frequency oscillation in Gansu Longnan Bi- Cheng power system was analyzed, and the participation factors and modal distribution for each generator were calculated with eigen value analysis method. The parameters of PSS for generator unit of Bikou Hydropower Plant were set and calculated, and test of system low frequency oscillation on site was carried out, which verified the role of PSS for suppressing the low frequency oscillation of system.
