摘　　要：本文提出用描述函数法来分析具有比例式励磁调节器(AER)、电力系统稳定器(PSS)和最优励磁控制方式等三种励磁控制方式对电力系统静稳定性能的影响,并进一步探讨各种励磁调节系统中的任一环节参数改变对电力系统静稳定鲁棒性的影响,运行结果表明,此法比经典法有更多的优越性。The objective of the paper is to use the describing function method to analyse the influence of a proportional automatic excitation regulator (AER), a power system stabilizer (PSS) and a linear optional excitation regulator on the static stability of power systems. Besides these, the effect of the parameters of various kinds of excitation regulator systems on power system stability is also discussed. The results show that the method has more advantages than the classical and traditional methods.
