Abstract

This paper illustrates the application of a recently proposed time-domain method in the calculation of lightning-induced voltages by nearby cloud-to-ground lightning strikes on a realistic, large-scale distribution network using the JMarti model in the Alternative Transients Program (ATP). In this method, the effect of the incident electromagnetic fields on the illuminated lines is accounted for entirely in terms of independent current sources that are calculated only once for a given lightning event using data obtained from the built-in fitting tool available in ATP. The simulated large-scale network includes laterals, grounding points, surge arresters, transformers, and loads. It is shown that frequency-dependent line losses may have a significant effect on the voltages induced on different parts of the simulated network, and that they should not be neglected in this type of study.

基于JMarti模型的大型配电网雷击感应电压计算

本文介绍了最近提出的一种时域方法，利用备选暂态方案（ATP）中的JMarti模型，在实际的大型配电网中计算附近云对地雷击引起的雷击电压。在这种方法中，入射电磁场对照明线路的影响完全是根据独立电流源来计算的，这些电流源只对给定的闪电事件计算一次，使用ATP中可用的内置拟合工具获得的数据。模拟的大型网络包括横向、接地点、避雷器、变压器和负载。结果表明，频率相关的线路损耗可能对模拟网络不同部分的感应电压有显著影响，在这类研究中不应忽视它们。

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
