项目摘要

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 this proposal 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.Investigators possess necessary skills, facilities and expertise required to successfully perform the proposed research effort.

该提案涉及电网中机电波传播现象的宏观分析工具的开发。提出的建议和活动是基于他们之前对波传播理论的研究是有效的和被电力系统暂态分析所接受的假设。在这个建议中解决的问题是建立有效的模型来研究机电波在非常大的规模，广泛的网络上的传播。人们对这一现象知之甚少，但它可能对未来的国家电力系统产生重大的有害影响。pi利用他们丰富的相关经验来概述一种全面的新方法来建模和研究问题。建议将网络作为一个连续体来研究，其中源和汇与它们相关；物理特征位于特定的点上。利用在其他领域开发的工具，如等离子体中的波传播，以及同步卫星同步测量转子角度在大范围内的数据。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中获得连续体模型的时间技术。所提议的方法可以被证明是广泛适用的，并且随着结构调整朝着比过去所设想的更为复杂的业务发展而具有重要的用处。调查人员拥有成功执行拟议研究工作所需的必要技能、设施和专业知识。
