Abstract

The performance of transmission lines has a significant impact on reliability aspects of the power supply system of a country. The lightning back flashover effects are recognized as one of the major causes of transmission line outages. This paper focuses on studying the effect of Multi Chamber Insulator Arresters (MCIA) on lightning back flashover by transient modeling and subsequent simulation of a selected transmission line. Power System CAD (PSCAD) software program is utilized as the software tool for modeling and simulation of the 132 kV, Matugama-Kukule transmission line for this study. Simulation of the created transmission line model is carried out with and without MCIA to evaluate the improvements in lightning back flashover performance after installation of MCIAs in this transmission line. This analysis will contribute to improve the reliability of the Sri Lankan electrical power system.

架空输电线路多室绝缘子避雷器防雷的技术经济可行性

输电线路的性能对一个国家供电系统的可靠性有着重要的影响。雷电反闪络效应是引起输电线路中断的主要原因之一。本文通过对某输电线路的暂态建模和后续仿真，研究了多室绝缘子避雷器对雷电反闪络的影响。本研究使用电力系统CAD (PSCAD)软件作为132 kV, matugoma - kukuule输电线路的建模和仿真软件工具。对所建立的传输线模型进行了有和没有MCIA的仿真，以评估在该传输线中安装MCIA后对雷电反闪络性能的改善。这一分析将有助于提高斯里兰卡电力系统的可靠性。

期刊介绍： Development Engineering: The Journal of Engineering in Economic Development (Dev Eng) is an open access, interdisciplinary journal applying engineering and economic research to the problems of poverty. Published studies must present novel research motivated by a specific global development problem. The journal serves as a bridge between engineers, economists, and other scientists involved in research on human, social, and economic development. Specific topics include: • Engineering research in response to unique constraints imposed by poverty. • Assessment of pro-poor technology solutions, including field performance, consumer adoption, and end-user impacts. • Novel technologies or tools for measuring behavioral, economic, and social outcomes in low-resource settings. • Hypothesis-generating research that explores technology markets and the role of innovation in economic development. • Lessons from the field, especially null results from field trials and technical failure analyses. • Rigorous analysis of existing development "solutions" through an engineering or economic lens. Although the journal focuses on quantitative, scientific approaches, it is intended to be suitable for a wider audience of development practitioners and policy makers, with evidence that can be used to improve decision-making. It also will be useful for engineering and applied economics faculty who conduct research or teach in "technology for development."
