This paper addresses some practical issues at the stages of conducting the risk assessment and designing the external lightning protection system according to the IEC 62305 standards, for a twin-tower building. In a building complex of multiple structures, a significant difference in material and installation cost could be resulted depending on the fact that the complex is considered as a single building or several individual buildings. The standards do not specify a solid criterion for determining whether several adjacent buildings are considered as a single entity or multiple structures. The same issue may give rise to a strategically problematic scenario in designing the air-termination system for tall twin structures with different heights as IEC 62305–3 (2010) standards prescribe air-termination network down to 80% of the height of the building from the rooftop level, for buildings of height more than 60 m. The paper proposes a rational solution for overcoming the undetermined specifications pertinent to these cases.
本文介绍了某双塔建筑外部防雷系统按照IEC 62305标准进行风险评估和设计阶段的一些实际问题。在由多个结构组成的建筑群中,材料和安装成本的显著差异可能取决于该建筑群被视为单个建筑物或多个独立建筑物的事实。这些标准并没有明确规定确定几个相邻建筑是被视为一个实体还是多个结构的可靠标准。同样的问题可能会在设计不同高度的高层双体结构的空气终端系统时产生战略问题,因为IEC 62305-3(2010)标准规定,对于高度超过60米的建筑物,空气终端网络从屋顶下降到建筑物高度的80%。本文提出了一种合理的解决方案,以克服与这些情况有关的不确定规格。

This paper analyzes the overvoltages associated with direct strokes to a hybrid overhead line (138 kV and 13.8 kV circuits sharing the same structures). The voltages are calculated using the EMTP-RV, and their dependence on parameters such as the stroke current front time, soil resistivity, and impedance of the grounding system is discussed. Emphasis is given to the voltages on the medium-voltage circuit. A 1:20 scale model of a hybrid line has been implemented, and a good agreement has been found between measured and calculated voltages.

Distribution Network Impact Assessment with Geometrically Identified Strike Points: An Approach 具有几何识别打击点的配电网影响评估方法

This paper presents an algorithm to generate direct and indirect strike points for lightning impact assessments. The proposed method uses the Electrogeometric Model to define the strike range limit, such that the generated events fall inside the range that would cause insulation failure. In this way, the non-potential strike events are excluded before carrying out additional computations, without requiring any complex algorithm for the event filtration. This method has been implemented to assess 17 arrester-based protection schemes with different arrester spacings. The assessment revealed the overvoltage impact levels at different nodes of the network concerned in the case study. It is proposed that the commonly accepted fact that the impact level generally increases with the increasing arrester spacing, may not be always true. Instead, there can be a range of spacing distances with abnormalities. Also, it was noted that the severity ranking of the distribution transformers in the assessed network varied with the protection scheme. Thus, it is recommended to perform a prior analysis in implementing a planned protection scheme.
本文提出了一种用于闪电影响评估的直接和间接雷击点生成算法。该方法利用电几何模型来定义冲击范围限制,使所产生的事件落在导致绝缘失效的范围内。这样,在进行额外的计算之前,就排除了非潜在的罢工事件,而不需要任何复杂的事件过滤算法。该方法已用于评估17种不同避雷器间距的基于避雷器的保护方案。该评估揭示了案例研究中有关网络不同节点的过电压影响水平。人们普遍认为,冲击水平通常随着避雷器间距的增加而增加,这一事实可能并不总是正确的。相反,可能有一系列的间隔距离与异常。此外,还注意到评估网络中配电变压器的严重等级随保护方案的不同而不同。因此,建议在实施计划保护方案时进行事先分析。

This paper presents the result of the same model of survey applied in Malaysia and Brazil, two countries with a high keraunic density of lightning in most territory. This survey had as main objective to be applied to a lay public and with little technical knowledge about lightning in order to verify the general knowledge of the population and its main beliefs and myths. The questionnaire was released to be answered through the Google Form tool. The total number of responses obtained was 928, the vast majority by people from the state of São Paulo (~70%) and with a high level of education (~80% with higher or postgraduate degrees). This sampling was not very good because we would like to have a more comprehensive sampling in terms of the various Brazilian states and also regarding the education that did not reflect the Brazilian population in general. Thus, the research result was impaired, reflecting only a small part of the Brazilian population. Despite this, for the public that the research reached, even with high education, the result of the research suggests the need for a great effort of communication about the dangers that involve the occurrence of lightning and the good practices of behavior in front of them. At this point, there is a divergence from the Malaysian survey, which has a more uniform instruction and the same level of responses.
本文介绍了在马来西亚和巴西这两个地区闪电密度较高的国家所采用的相同模式的调查结果。这项调查的主要目的是应用于对闪电缺乏技术知识的外行公众,以核实人口的一般知识及其主要信仰和神话。问卷发布后,通过Google Form工具进行回答。获得的回复总数为928,绝大多数来自圣保罗州(~70%)和具有较高教育水平(~80%具有更高或研究生学位)的人。这个抽样并不是很好,因为我们希望有一个更全面的抽样,从巴西各州的角度来看,也从教育的角度来看,这并不能反映巴西人口的总体情况。因此,研究结果受到损害,只反映了巴西人口的一小部分。尽管如此,对于研究涉及的公众来说,即使受过高等教育,研究结果也表明,需要付出很大的努力,就闪电发生的危险以及在闪电面前的良好行为进行沟通。在这一点上,与马来西亚的调查有所不同,马来西亚的调查有更统一的指导和相同水平的回答。

This paper mainly analyzes the development process of a natural upward lightning flash initiated from a wind turbine in Zhangbei wind farm in 2019 using optical data. The duration of the flash was more than 283 ms, and there are totally 7 return strokes with their peak current varied from -8.1 kA to -18.7 kA. The average 2-D speed of the leaders preceding all 7 return strokes is greater than 106 m/s, with the leader preceding RS6 being the slowest at 2.6 x 105 m/s and RS5 being the fastest at greater than 1.1 x 106 m/s. There is a significant linear positive correlation between the sum of relative luminance integral and the cut-off time of each RS, and the corresponding R2 is 0.96.

In this paper the electromagnetic compatibility (EMC) considerations made to the direct lightning current measuring system that is part of the Johannesburg Lightning Research Laboratory (JLRL) are presented. The output voltages from two series connected shunts and the sending of their analog signals downward a tower to the measuring system, makes this measuring setup particularly critical regarding immunity against the strong effects of the lightning current.

As wind power becomes main driver towards energy transition, offshore power plants will be significant contributors. This paper investigates the effects of lightning strikes in an offshore wind power plant which consists of two wind turbines. Its location is in Northern Europe and the current investigation is focusing on potential impact on its main components. The foundation of the offshore wind turbines is gravity based which is suitable for low depth waters. The impact on the main components is evaluated considering four cases of lightning strikes hitting the tip of the blade via simulation in the ATP - EMTP software while important results are received.

Lightning Ground Potential Rise - A Contributing Factor to Damage Associated with Wind Turbine Blades 闪电接地电位上升-风力涡轮机叶片损坏的一个重要因素
Pub Date : 2022-10-02 DOI: 10.1109/ICLP56858.2022.9942554
P. H. Pretorius
The international standard IEC 61400–24, addressing specifically lightning protection of wind energy systems, was introduced in 2010 with a revision and update of the standard published in 2019. This international standard presents guidance, through high voltage and high current tests, on the specific evaluation of wind turbine blades against lightning damage. Despite this guidance, a significant number of blade-damage-cases are still being reported, making it an important consideration in view of the growing number of wind farms employed in renewable energy projects worldwide. This paper indicates that lightning ground potential rise, including travelling waves and reflections from the foundation of the wind turbine and other bonded parts of the wind turbine, can set up potentials inside the blade that are large enough in magnitude to cause the breakdown of the composite material which the blade is manufactured from. Potentials set up in this manner are not tested for under the existing test regime covered by IEC 61400–24. The paper further shows the importance of earthing / bonding and protection of specific components, such as sensors, heating systems and carbon strips applied in the blade. When not done correctly, the implication includes mis-assignment of the lightning protection zone inside the blade, as recommended by secondary standards / specifications, and an underestimation of the lightning risk associated with the wind turbine blades. Based on the findings of this paper, it is strongly recommended that the testing techniques covered in IEC 61400–24 should be updated to incorporate the anticipated damage mechanism presented by ground potential rise (and associated travelling waves and reflections). This will require some form of model of the entire tower plus the foundation and accompanying soil conditions.
专门针对风能系统防雷的国际标准IEC 61400-24于2010年推出,并于2019年发布了该标准的修订和更新。本国际标准通过高压和大电流试验,对风力涡轮机叶片抗雷击损伤的具体评估提供指南。尽管有这一指导方针,但仍有相当数量的叶片损坏案例被报道,鉴于全世界可再生能源项目中使用的风力发电场数量不断增加,这是一个重要的考虑因素。本文指出,雷电地电位上升,包括来自风力机基础和风力机其他粘结部件的行波和反射,可以在叶片内部形成足够大的电势,从而导致制造叶片的复合材料击穿。在IEC 61400-24现有的测试制度下,不测试以这种方式设置的电势。本文进一步展示了接地/粘接和保护特定部件的重要性,例如传感器,加热系统和叶片中应用的碳带。如果做得不正确,其含义包括按照二级标准/规范的建议,错误地分配叶片内部的防雷区域,以及低估与风力涡轮机叶片相关的雷击风险。基于本文的发现,强烈建议更新IEC 61400-24中涵盖的测试技术,以纳入地电位上升(以及相关的行波和反射)所呈现的预期损伤机制。这将需要整个塔的某种形式的模型,加上基础和伴随的土壤条件。

Pretorius","doi":"10.1109/ICLP56858.2022.9942554","DOIUrl":"https://doi.org/10.1109/ICLP56858.2022.9942554","url":null,"abstract":"The international standard IEC 61400–24, addressing specifically lightning protection of wind energy systems, was introduced in 2010 with a revision and update of the standard published in 2019. This international standard presents guidance, through high voltage and high current tests, on the specific evaluation of wind turbine blades against lightning damage. Despite this guidance, a significant number of blade-damage-cases are still being reported, making it an important consideration in view of the growing number of wind farms employed in renewable energy projects worldwide. This paper indicates that lightning ground potential rise, including travelling waves and reflections from the foundation of the wind turbine and other bonded parts of the wind turbine, can set up potentials inside the blade that are large enough in magnitude to cause the breakdown of the composite material which the blade is manufactured from. Potentials set up in this manner are not tested for under the existing test regime covered by IEC 61400–24. The paper further shows the importance of earthing / bonding and protection of specific components, such as sensors, heating systems and carbon strips applied in the blade. When not done correctly, the implication includes mis-assignment of the lightning protection zone inside the blade, as recommended by secondary standards / specifications, and an underestimation of the lightning risk associated with the wind turbine blades. Based on the findings of this paper, it is strongly recommended that the testing techniques covered in IEC 61400–24 should be updated to incorporate the anticipated damage mechanism presented by ground potential rise (and associated travelling waves and reflections). This will require some form of model of the entire tower plus the foundation and accompanying soil conditions.","PeriodicalId":403323,"journal":{"name":"2022 36th International Conference on Lightning Protection (ICLP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124760199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we report on recent progress in application of numerical modeling for development of Line Lightning Protection Devices. The ability of previously developed arc model to predict the current interruption capability of certain LLPD designs is demonstrated on real LLPD prototypes tested in high-voltage laboratory. As a case of particular design improvement we describe the calculation of optimal value of LLPD additional chamber volume.
