“…Esse problema pode ser anunciado da seguinte forma: dada uma LT, quais são os pontos em que os para-raios deverão ser posicionados de forma a proteger a linha e, simultaneamente, garantir uma solução viável economicamente. Até o momento atual, poucos trabalhos tocam esse problema na perspectiva da otimização (Kezunovic e Dokic, 2018;Shariatinasab e Azimi, 2020;Castro et al, 2022).…”

The application of transmission line surge arresters (TLSAs) is one of the main approaches found to boost the performance of overhead transmission lines (OHTLs) against atmospheric discharges. Thus, this work proposes a methodology for the optimal placement of TLSAs in OHTLs based on the combination of an optimization algorithm -inspired by General Variable Neighbourhood Search and Genetic Algorithm -and the ATP (Alternative Transient Program). The line performance estimation is made considering the little cited transfer effect of the atmospheric surge due to arresters operation. At the end, in order to analyze the functioning of the proposed procedure, experiments are carried out to optimize the positioning of TLSAs in two OHTLs. It may be inferred from the results that directing search considering the lightning surge transfer effect and favoring the positioning of TLSAs in the lowest phase(s) can reduce the amount of arresters necessary to satisfy the performance constraints, or at least diminish the application computational cost. Resumo: A instalação de para-raios é uma das principais abordagens encontradas para melhorar o desempenho de linhas de transmissão (LTs) frente às descargas atmosféricas. Assim sendo, este trabalho propõe um modelo para otimizar a alocação de para-raios em LTs baseado na junção entre um algoritmo de otimização inspirado na meta-heurística busca em vizinhança variável geral e no algoritmo genético com o software ATP. A estimativa de desempenho da linha é feita tendo em conta o pouco citado efeito de transferência do surto atmosférico devido à operação dos para-raios. Com o objetivo de verificar o funcionamento da metodologia são realizados experimentos que otimizam o posicionamento de para-raios em duas LTs. Infere-se dos resultados que o direcionamento da busca considerando o efeito de transferência de surto e o favorecimento à alocação de para-raios nas fases mais baixas pode reduzir a quantidade de para-raios necessária para se atender aos limites de desempenho, ou ao menos reduzir o custo computacional da aplicação.

“…In this work, PSCAD/EMTDC programming is used for creating a computer simulation model of a 220 kV transmission line in actual operation [5] to evaluate the effect of different grounding resistances and different arrester configurations on the line's lightning resistance performance when lightning strikes occur [6]. Based on the analysis results, the optimal lightning resistance performance of the arrester configuration scheme under different grounding resistances is obtained.…”

Lightning strikes are a major cause of insulator flashover and line tripping; hence, improving line lightning resistance is essential. This article establishes a 220 kV transmission line model in PSCAD/EMTDC and examines the effect of alternative grounding resistance and phase arrester configurations on lightning resistance levels. The analytical findings demonstrate that the transmission line’s lightning resistance level is inversely connected with its ground resistance. When ground resistance cannot be lowered, lightning resistance can be improved by adding a lightning arrester. The lightning resistance level of each arrester arrangement varies depending on the ground resistance circumstances. An appropriate configuration policy must be picked depending on the site characteristics. The study results in this research give a specific reference for lightning protection transformation of 220 kV transmission lines.

“…T HIS paper primarily focuses on equipment quality inspection of surge arresters. As an essential overvoltage protection devices in power systems, surge arresters are designed to suppress overvoltages (including operational overvoltages and lightning-induced overvoltages), release high currents, and prevent protected equipment from being damaged by lightning-induced overvoltages or operational overvoltages [1]- [3]. Surge arresters not only affect the ability of power systems to operate safely and stably but also impact their economic efficiency, especially in the construction of extrahigh voltage and ultra-high voltage systems.…”

The quality of power grid equipment forms the material foundation for the safety of the large power grid. Ensuring the quality of equipment entering the grid is a core task in material management. Currently, the inspection of incoming materials involves the generation of sampling plans, sampling, sealing, sample delivery, and testing. Due to the lack of a comprehensive control system and effective control measures, it is not possible to trace the execution process of business operations afterward. This inability to trace hampers the investigation of testing issues and risk control, as it lacks effective data support. Additionally, a significant amount of original record information for key parameters in the testing process, which is based on sampling operation standards, has not been effectively utilized.To address these issues, we conduct researches on key monitoring technologies in the typical material inspection process based on the Internet of Things (IoT) and analyze the key parameters in inspection results. For purpose of complete the above tasks, this paper investigates the use of Long Short-Term Memory (LSTM) algorithms for quality prediction in material equipment based on key inspection parameters. In summary, this paper aims to provide professional and reliable quality data support for various business processes within the company, including material procurement, engineering construction, and equipment operation.
