摘要
本文介绍了首次应用辨识方法于电力系统实时在线测试低频振荡。利用这种方法可以随时研究运行系统的低频振荡情况。１９９１年１０月试验证实了网络中的ＳＸＫ电厂是该系统的低频振荡源。
The principle and testing scheme of a novelon-line method of identifying the lower frequency oscillationin power system is presented in this paper. For the firsttime, the application of this on-line method to test the lowerfrequency oscillations in power system is described. Usingthe method the lower frequency oscillation in operating system can be studied at any time. According to the result ofusing this method in Oct. 1991 in Fujian power system, itwas confirmed that the SKX hydroelectric power station wasthe source of lower frequency oscillation in this system.
