本文利用被动性理论解释耗散能量流法，分析其缺陷并提出改进框架。
摘要：
尽管相量测量单元技术已广泛部署，但在电力系统中定位低频强迫振荡源仍是一个开放性研究课题。耗散能量流法是一种源定位技术，在模拟和实时应用中在ISO New England表现优异。然而，该方法存在一些缺陷，目前仍不明确。本文借鉴控制文献中的被动性和正实性概念，以解释耗散能量流法，明确其缺陷原因，并建立改进该方法的框架。本文提出的定理通过在简单无限 bus 功率系统模型上的仿真进行测试。
英文摘要：
Despite wide-scale deployment of phasor measurement unit technology, locating the sources of low frequency forced oscillations in power systems is still an open research topic. The dissipating energy flow method is one source location technique which has performed remarkably well in both simulation and real time application at ISO New England. The method has several deficiencies, though, which are still poorly understood. This paper borrows the concepts of passivity and positive realness from the controls literature in order to interpret the dissipating energy flow method, pinpoint the reasons for its deficiencies, and set up a framework for improving the method. The theorems presented in this paper are then tested via simulation on a simple infinite bus power system model.
