摘　　要：山西电网低频振荡分析运用改进的Arnoldi频域方法,计算特高压(1000 kV)试验示范线路投运前后山西电网在各种运行方式下的阻尼特性,找出大区联网后山西电网的薄弱环节,确定PSS(电力系统稳定器)的合理投入地点。The low frequency oscillations analysis item in Shanxi Power Network uses the improved Amoldi method to calculate the clamping property of Shanxi Power Network in different operation modes after the line of ultra-high voltage test and demonstration before and after run. Find out the weakness tache of Shanxi Power Network after section and section join, and make sure the power system stabilizer＇s placed station.
