摘　　要：分析了几种励磁限制和电力系统稳定器(PSS)介入自动电压调节器的方式对小扰动稳定性的影响,提出了弱联系系统及带有PSS以比较门方式介入电压调节器的低励限制有可能削弱小扰动稳定性,需要考虑低励限制环参数和PSS的参数以提高小扰动稳定性。Analyse effect of several modes that connected generator excitation restriction and PSS to AVR on small disturbance stability, bring forward possible weaken small disturbance stability in the comparative mode that underexcitation restriction connect to AVR with PSS, in the case, must consider the parameters of underexcitation restriction and PSS.
