摘要
本文介绍了PSS定义、原理及作用,分析了某电厂两种不同的励磁系统PSS模型的区别,通过PSS试验得出了电厂PSS投入运行,增加了系统的阻尼,对系统中可能出现的0.2~2.5Hz区域间低频振荡具有较好的抑制作用。
This paper introduces the definition, principle and function of PSS. Analysis of the difference between two kinds of excitation system PSS model of a Power Plant. Through the PSS test shows the PSS of power plant put into operation, increases the damping of the system. On may appear in the system of 0.2 ~ 2.5Hz inter area low frequency oscillation has better inhibition action.
