提出了一种真实的实时稳定性在线监测方案。建议的稳定性监测系统是通过使用一台个人计算机（PC）与AD转换接口。为了研究监测结果的准确性，在模拟仿真器上进行了实验研究。在模拟仿真器上进行了四机无限总线系统的测试。测试系统有两种振荡模式：与单个单元相关的超过1 Hz的高频局部模式和0.3至0.4 Hz的低频全局模式。利用所提出的在线监测系统，可以准确地识别出这两种典型模态的阻尼和频率。
This paper presents an on-line real time stability monitoring scheme. The proposed stability monitoring system is set up by using a personal computer (PC) with AD conversion interface. To investigate the accuracy of the monitored results, experimental studies has been performed on an analog simulator. A four-machine infinite-bus system was utilized for the tests on the analog simulator. The test system has two modes of oscillations: high frequency local modes beyond 1 Hz related to individual unit, and a low frequency global mode from 0.3 to 0.4 Hz. The damping and the frequency of these two typical modes are identified accurately by using the proposed on-line monitoring system.
