摘要/Abstract

摘要： 电力系统稳定器PSS是一闭环运行的控制器,传统的参与因子配置法只考虑了PSS输入信号的可控可观性,当系统负载较重时,得到的配置结论可能不合理。考虑PSS输入信号和输出信号馈入侧2方面的影响,提出了电力系统稳定器配置的综合参与因子法。最后以4机2区系统为例,分析了运行方式改变对PSS控制效果的影响,并利用综合参与因子法选择了PSS配置机,该方法适用于重载系统,比传统的参与因子配置法更有效。

关键词: 电力系统稳定器, 低频振荡, 参与因子, 综合参与因子

Abstract: Power System Stabilizer (PSS) in power system is a closed-loop controller. However, the traditional participation factor method for configuration location selection only considers controllability and observability of PSS input signal. It may give misleading results under heavy load condition. A composite participation factor method is proposed to identify the most effective location selection of generating units to be equipped with power system stabilizers, which takes into account both controllability, observability of input signal and feedback control effect of power system stabilizer. The case study with a two-area, four-generator system confirms that the proposed method can provide more effective location for power system stabilizer especially under heavy load condition, which is more effective than traditional participation factor method.

Key words: power systems stabilizer, low frequency oscillation, participation factor, composite participation factor
