摘　　要：从发电机Heffron-Philips模型出发,分析发电机及励磁系统在涵盖有功低频振荡和轴系扭振在内的0.1~40Hz范围内无补偿相频特性,同时给出电力系统稳定器模型(PSS-1A、PSS-2B和PSS-NB)在0.1~40Hz的相频特性,并从理论上分析其在大型发电机组发生高频轴系扭振时的阻尼特性,最后通过一个高频零阻尼RTDS仿真系统进行验证。Based on the Heffron-Philips model of generator,the uncompensated phase frequency characteristics of generator and its excitation system in the range of 0.1~40Hz,including active low-frequency oscillation and shaft torsional vibration,are analyzed.The phase frequency characteristics of power system stabilizer models(PSS-1A,PSS-2B and PSS-NB)in the range of 0.1~40Hz are given,and their damping characteristics in the case of high-frequency shaft torsional vibration of large generator set are theoretically analyzed.It is verified by a high frequency zero damping RTDS simulation system.
