摘要
利用收敛性能更为优越的稀疏特征值分析方法——隐式重启动Arnoldi法(IRA)编制的SSAPV1.0软件,对南方大规模交直流并联运行的电网进行了小干扰稳定分析,找出了存在的弱阻尼模式。根据参与因子在强相关机组加装电力系统稳定器(PSS),同时采用直流调制。结果表明,PSS和直流调制能够显著增强系统阻尼,从而有效地抑制了低频振荡。
South China Power System is a typical AC-DC interconnected power system. This paper presents the results of small signal stability analysis of South China Power System with a sparse eigenvalue analysis method IRA, which has fast convergence. The countermeasures are selected after the weak damping modes are found： such as adding PSS on generators with high participation factors and applying HVDC modulation. It shows that the system damping can be increased and the low frequency oscillation can be suppressed by PSS and HVDC modulation.
