Abstract

The 150 kV Substation is a vital element within the electrical power transmission system, serving as a critical link between power generation and the distribution of electricity to consumers. Given its essential role, the continuity of substation operations must be safeguarded against various potential disturbances, one of which is lightning strikes. Lightning can cause equipment damage, operational disruptions, and even large-scale power outages. Therefore, the lightning protection system plays a crucial role in maintaining the reliability and safety of the electrical system within the substation. This study discusses the role of lightning protection systems, covering their working principles, types of protective devices such as lightning arresters, grounding systems, and effective installation strategies. Through technical analysis and evaluation of protection standards, it is found that the proper implementation of lightning protection systems can reduce equipment damage risk by more than 70% and enhance the continuity of power supply services. Furthermore, factors such as ground resistance, lightning strike density, and arrester placement are identified as key parameters in designing an optimal protection system. This study emphasizes that improving the quality of lightning protection systems must be accompanied by regular maintenance and comprehensive performance evaluations to ensure sustained effectiveness. Consequently, substations can operate more reliably and safely, thereby supporting the stability of the national electrical grid.

Review

This paper, titled "The Role of Lightning Protection Systems in the Electrical System of 150 kV Substations," addresses a critically important topic within electrical power engineering. The abstract clearly articulates the essential role of 150 kV substations in the power transmission network and the significant threats posed by lightning strikes, which can lead to equipment damage, operational disruptions, and widespread outages. By focusing on lightning protection, the study aims to safeguard the continuity and reliability of these vital installations, thereby contributing directly to national grid stability. The stated objective of discussing working principles, protective devices, and installation strategies is highly relevant to both practitioners and researchers in the field. The abstract highlights several key strengths, particularly its comprehensive scope in covering various aspects of lightning protection systems, including lightning arresters, grounding systems, and effective installation strategies. A significant claim is made regarding the quantifiable benefits of proper implementation, stating a potential reduction in equipment damage risk by over 70% and an enhancement in power supply continuity. This finding, if rigorously supported by the full manuscript, offers a compelling justification for investment in robust protection measures. Furthermore, the identification of ground resistance, lightning strike density, and arrester placement as crucial design parameters demonstrates a practical understanding of the factors influencing an optimal protection system. While the abstract effectively establishes the importance and scope, future iterations or the full manuscript would benefit from greater clarity on the specific methodology employed to arrive at its conclusions, especially the quantitative claim of a 70% risk reduction. Details on whether this stems from theoretical modeling, empirical data analysis, specific case studies, or a comprehensive literature review would significantly strengthen the paper's scientific rigor. Additionally, while emphasizing regular maintenance and performance evaluations is crucial, the paper could further explore specific best practices or frameworks for achieving sustained effectiveness. Nonetheless, the paper provides a valuable foundational discussion on a vital subject, offering practical insights that could significantly inform substation design and operational strategies.
