摘　　要：通过对日照电厂350MW机组励磁系统的分析研究,确定了励磁装置的实际数学模型。经过SME仿真计算,初步选定PSS的参数。现场试验表明,经过仿真计算得出的PSS参数是适合的。现场试验采用了有PSS及无PSS情况下,AVR输入不同频率的干扰信号,测量发电机功率振荡的衰减,试验结果表明,该方法对测定不同频率时PSS的阻尼特性是有效的。Based o n analysis of excitation system for350MW units in Rizhao Power Plant ,the ma thematic model for excitation de-vice is presented.PSS parameters are selected by calculating of SME simulation,and the site test shows that the settings of PSS pa-rameters are suitable.With and without PSS at site test,the interfer ence signal in different frequencies is input into AVR,and the attenuation of power oscillation for generator is measured.The test results indicate that thi s method is effective on measuring damping feature of PSS in different frequenc ies.
