Discussion of several analytical approaches and tools about subsynchronous resonance 幾種次同步振蕩分析方法和工具的闡述
subsynchronous resonance ( ssr ) is a quite hazardous state easily encountered in power systems 次同步振蕩(ssr)是電力系統(tǒng)運行中可能出現(xiàn)的一種相當危險的狀態(tài)。
Then the different behaviors between fixed series capacitor and tcsc are compared aiming at ssr, when they are individually applied to typical model of ieee second benchmark on subsynchronous resonance 繼而以ieeesecondbenchmarkonsubsynchronousresonance典型模型為例,比較了固定電容串補與可控串聯(lián)補償在模型系統(tǒng)中針對同步發(fā)電機次同步振蕩這一行為所造成的差異表現(xiàn)。
This paper studies two tcsc study systems, a tcsc system based on ieee first benchmark model ( ieee fbm ) and a simplified yi-feng 500kv tcsc study system, with ssr eigenvalue analysis in the platform of psaspfmsst . it proves the funtion of tcsc to mitigate subsynchronous resonance ( ssr ) . it also analyzes the influence of thyristor triggering algorithm of tcsc on ssr mitigation 本文在psasp小干擾線性化平臺psaspmsst上,對基于ieeefirstbenchmarkmodel(ieeefbm)的tcsc系統(tǒng)及簡化的伊馮500kv可控串補研究系統(tǒng),進行了ssr小干擾穩(wěn)定分析,驗證了tcsc對次同步諧振(ssr)的抑制作用,并研究了觸發(fā)算法對tcsc抑制ssr能力的影響。
