ECS-9807529 Kostelich This project is an application of chaos theory from mathematics to electric power engineering. The project focuses on the research on the design, formulation, and performance of electrical load models that employ chaos. The objective is to design a load model for certain highly varying loads such as AC electric arc furnaces, steel rolling mills, plasma torches and certain other mining loads, and electric arc welders. These loads have been shown to have load currents that are time series that exhibit chaos: that is, tests for chaos have been applied to field measurements and it appears that the load current data are consistent with a chaotic system as the generating source. The principal investigators span two universities (Arizona State University and Iowa State University) and two departments (Electrical Engineering and Mathematics) with the plan to combine facilities, talents, and capabilities to study chaotic models for the cited application. The research plan is to test chaotic models for applicability and accuracy with respect to field data and other models (namely, the stochastic model). The method of comparison and evaluation is through the use of advanced power quality indices, measures from the mathematics of chaos, and time and frequency domain evaluations. Actual AC arc furnace data shall be used in the evaluation and accuracy assessment. This project builds on the work of the co-principals. Some application oriented work was completed for the Electric Power Research Institute; however, that sponsor was primarily interested in applications and software development. Virtually no theoretical work nor fundamental research was done. This project proposes the fundamental research on the use of chaos models for highly varying electrical loads. The practical impacts of this work are: the utilization of chaos for a load model which may represent certain load types more accurately and more like the actual physical process; the development of accurate lo ad models for certain types of highly varying loads; and a new application of chaos theory for the measurement of the impact of highly varying electrical loads. Also, there is an educational component to the project and there is expected to be an impact on the students, both graduate and undergraduate, who are involved in the project. This will be in the understanding and utilization of chaos theory. Part of the implementation of the educational component of the project is the development of a classroom study module on chaos.

ECS-9807529 Kostelich 该项目是混沌理论从数学到电力工程的应用。 该项目的重点是研究采用混沌的电力负荷模型的设计，制定和性能。 目标是为某些高度变化的负载设计负载模型，例如AC电弧炉、轧钢米尔斯、等离子炬和某些其他采矿负载以及电弧焊机。 这些负载已被证明有负载电流的时间序列，表现出混沌：也就是说，测试混沌已被应用到现场测量，它出现的负载电流数据是一致的混沌系统作为生成源。 主要研究人员跨越两所大学（亚利桑那州立大学和爱荷华州州立大学）和两个部门（电气工程和数学）的计划，联合收割机的设施，人才和能力，研究混沌模型的引用应用。 研究计划是测试混沌模型的适用性和准确性方面的现场数据和其他模型（即，随机模型）。 比较和评估的方法是通过使用先进的电能质量指标，混沌数学的措施，以及时域和频域评估。 在评估和准确性评定中应使用实际交流电弧炉数据。 该项目以共同负责人的工作为基础。 电力研究所完成了一些面向应用的工作;然而，该赞助商主要对应用和软件开发感兴趣。 实际上没有进行任何理论工作或基础研究。本计画提出将混沌模型应用于高度变化之电力负荷之基础研究。 这项工作的实际影响是：利用混沌的负荷模型，可以更准确地代表某些类型的负荷，更像实际的物理过程;准确的负荷模型的发展，为某些类型的高度变化的负载;和一个新的应用混沌理论的影响，高度变化的电力负荷的测量。 此外，该项目还有一个教育部分，预计将对参与该项目的研究生和本科生产生影响。 这将是对混沌理论的理解和运用。 该项目教育部分的部分实施工作是开发一个关于混乱的课堂研究模块。
