Pss参数的三维曲面阻尼特性

DAMPIING CHARACTERIST ICS OF THREE-CURVED SURFACE OF POWER SYSTEM STABILIZER PARAMETERS

本文分析了励磁系统全阶模型（ＩＥＥＥ－Ｉ－型包括二级Ｐｓｓ）参数的阻尼特性。确定了参数的综合阻尼系数立体曲面图；设计了Ｐｓｓ最佳参数．为现场调试和工程设计提供了方便和依据和根轨迹法设计参数进行了比较并进行了动态时间的仿真计算。认为按“η”选择Ｐｓｓ参数的效果是显著的，要比极轨迹法选择参数好的多。

This thesis analysises the comprehensive damping characteristics of the excitaion ofsynchronous generators and design parameters of the excitaion control systems' It definites three-curved surface figure of the comprehensive damping, provides convenienceand basis for adjuster and designer. All things considered that comprehensive dampingcoefficient-method Seems to be more effective than the Root Locus-method,aftcr the optional vane calculation of the excitation parameters is made.
