| 摘 要： | 利用单机无穷大系统小干扰线性化模型从理论上分析了应用快速高增益励磁调节器后系统产生低频振荡的原因。对PSS抑制低频振荡的原理——相位补偿进行了分析。讨论了PSS的各个环节功能及参数对阻尼低频振荡的影响，并给出了某发电机组PSS相位校正的实测数据，证明PSS对低频振荡有良好有效的抑制作用。

| Abstract: | This paper analyzes the reason of low freguency oscillation in power system which applies the fast and high-gain excitation regulator theoretically using the one-machine infinite-bus system small disturbance linear model.The principle of PSS damps low frequency oscillation,phase compensation,is presented and the function of PSS's parts and the effect of parameters to damping the low frequency oscillation are also discussed.The phase compensation field-test data and calculation results of PSS show that PSS can damp low frequency oscillation effectively. |
