0217829OjoThis award supports a three-year collaborative research project between Professor Joseph O. Ojo, with the Department of Electrical Engineering at Tennessee Technological University, and Professor Michael O. Omoigui, with the Department of Electronic and Electrical Engineering at Obafemi Awolowo University in Nigeria. The investigators will study power flow control and stability improvement in longitudinal power systems using power flow controllers.Electric power systems in many developing countries are usually small and radial/longitudinal with little connectivity, making them operate like isolated systems. They are susceptible to lengthy time interruptions, fluctuations in voltage currents, and poor voltage regulation, and as a result the transmission and distribution systems are generally overloaded. Nigeria is moving away from the more traditional mechanical power systems towards a more electronic system that will use converter-based devices, which can then offer greater flexibility and improved operation. The investigators will develop models for the power systems, and use them to analyze the power systems' performance using a unified power flow controller under varying conditions. As part of the project, they will study the use of multi-terminal, converter-based power flow controller topologies to improve power flow capability and enhance the voltage system stability of weak and longitudinal power systems, especially in a deregulated environment. This project combines Dr. Ojo's expertise in power electronics with Dr. Omoigui's knowledge of power system analysis and control.Currently in the United States little study is being done on the unique problems of small and longitudinal power systems, but they will become increasingly important as more US power systems become deregulated. It is anticipated that the results of this project will provide viable and efficient solutions to perennial power system disturbances that are common in longitudinal power systems. Both investigators have a strong record in graduate education, and they also expect that a significant amount of knowledge transfer will occur among their students as a result of this project.The Office of International Science and Engineering and the Division of Electrical and Communications Systems are jointly supporting this project.

0217829ojothis奖与田纳西理工大学的电气工程系和迈克尔·OMOIGUI教授与尼日利亚Obafemi Awolowo大学的电子和电气工程系与Electric and Electric Engineering系的迈克尔·O·OmoiGui教授支持约瑟夫·OJO教授之间的为期三年的合作研究项目。 研究人员将使用功率流控制器研究纵向动力系统的功率流控制和稳定性。许多发展中国家的电力系统通常是小的，径向/纵向的，连通性几乎没有连接，使它们像孤立的系统一样运行。 它们容易受到延长的时间中断，电压电流的波动以及电压调节较差的影响，因此，传输和分配系统通常过载。 尼日利亚正在从更传统的机械电源系统转向使用基于转换器的设备的更电子系统，然后可以提供更大的灵活性和改进的操作。 调查人员将开发电源系统的模型，并使用它们在不同条件下使用统一的功率流控制器来分析电源系统的性能。 作为项目的一部分，他们将研究基于多末端的基于转换器的功率流控制器拓扑，以提高功率流能力并增强弱和纵向动力系统的电压系统稳定性，尤其是在放松管制的环境中。 该项目将Ojo博士在电力电子产品方面的专业知识与Omoigui博士的电力系统分析和控制知识相结合。目前，在美国，几乎没有研究小型和纵向电力系统的独特问题，但是随着更多的美国电力系统的说法，它们将变得越来越重要。 可以预料，该项目的结果将为多年生电力系统干扰提供可行，有效的解决方案，这些解决方案在纵向电源系统中很常见。 两位研究人员在研究生教育方面都有很强的记录，他们还希望由于该项目，学生之间将发生大量的知识转移。国际科学和工程办公室以及电气和通信系统的部门共同支持该项目。
