摘要
分析了PSS4B的模型、优点及参数设置,并利用MATLAB/Simulink建立了单机无穷大系统和双机系统模型,通过设置典型的故障及扰动,分别对无PSS、加装传统稳定器PSS1A、加装PSS4B三种系统运行方式进行仿真分析。结果显示新型稳定器PSS4B能够有效地抑制区域模式下的低频振荡,且其时域仿真曲线的振幅与振荡次数更小,优于传统的稳定器。
The PSS4B model, advantages and parameter settings are briefly analyzed. Then the MATLAB/Simulink is been used to establish a single-machine infinite-bus system and a tow-machine transmission system, by setting typical fault and disturbance, simulate three modes of without PSS, the installation of the ordinary PSS1 A, the installation of the PSS4B. The results show that the new stabilizer PSS4B can effectively suppress the low-frequency oscillation un- der inter-area mode. Moreover, the PSS4B simulation curve has smaller amplitude and oscillation number, better than the ordinary one.
