Electromechanical Wave Propagation in Large Electric Power Systems

这项提议与EPDT项目主任James Mink博士共同评估为本质上真正一体化的系统。它借鉴了机电波传播的思想，为大规模电力系统的暂态稳定分析提供了一种新的方法。该提案涉及开发用于分析电力网络中的机电波传播现象的宏观尺度分析工具。所提出的建议和活动是基于这样的假设，即他们以前对波传播理论的研究对于电力系统暂态分析是有效的和被接受的。在这些建议中解决的问题是开发有效的模型来研究超大规模、广泛的网络中的机电波传播。人们对这种现象知之甚少，但可能会在未来对国家电力系统产生重大有害影响。私人投资主任利用他们丰富的相关经验，勾勒出一种全面的新方法来模拟和研究这一问题。建议将网络作为一个连续体来研究，其中源和汇与其相关；物理特征位于特定的点上。利用了在其他领域开发的工具，如等离子体中的波传播，以及可获得基于卫星的同步测量大范围转子角度的数据。这个项目的工作已经进行了几年，其中已经开发了从实时系统数据获得连续模型的时间技术。随着重组朝着比过去设想的更复杂的操作迈进，拟议的方法可能会被证明是广泛适用的，并具有重要的用处。

This proposal was jointly assessed with the EPDT Program Director Dr. James Mink as truly Integrative Systems in nature. It draws on the ideas from the electromechanical wave propagation for a novel approach to the transient stability analysis problem in large-scale electric power systems. The proposal deals with development of a macro-scale analytical tool for electromechanical wave propagation phenomena in electric networks. The proposal and the activity proposed are based on the assumption that their previous research on the wave propagation theory is valid and accepted for power system transient analysis. The problem addressed in these proposals is that of developing efficient models for the study of electromechanical wave propagation on very large scale, extensive networks. This phenomenon is poorly understood, but could have significant harmful effects on the national power system in the future. The PIs draw on their extensive relevant experience to outline a comprehensive novel approach to modeling and studying of the problem. The proposal is to study the network as a continuum in which sources and sinks with their pertinent; physical characteristics are located at specific points. Tools developed in other fields, such as wave propagation in plasmas, are utilized, along with the availability of data from synchronized satellite-based simultaneous measurement of rotor angles over wide areas. Work on this project has been underway for several years, in which time techniques have been developed for obtaining the continuum model from real time system data. The proposed methodology could turn out to be widely applicable and of significant usefulness as restructuring advances toward much more complex operation than has ever been envisioned in the past.
