摘要
近年来,电力系统低频振荡问题已成为制约远距离传输容量的最主要因素之一。电力系统稳定器(PSS)是抑制低频振荡的最有效措施,电力系统稳定器的配置方案成为研究的焦点。提出一种prony方法来研究PSS的配置,prony方法的输入信号是基于全球定位系统(GPS)的广域测量系(WAMS)。仿真算例表明,该算法能够在线辨识低频振荡模式,并且根据辨识结果配置的PSS能够有效地抑制低频振荡。
In recent years, the power system low frequency oscillation has become one of the crucial factors which restrict longdistance transmission capacity. Power System Stabilizer (PSS) is the most effective measure to restrain lower frequency oscillation, the power system stabilizer configuration become focuses of researchers study. A prony method is proposed to study PSS configuration, the input signal come from wide-area measurement system (WAMS) based on the global positioning system (GPS). The example proves that this algorithm can identify the lower frequency oscillation and restrain lower frequency oscillation availably by configuring PSS based on result of the identifying information.
