  Abstract ▼

  The article provides a comprehensive analysis of the effectiveness of traditional and modern technologies for monitoring power transmission lines (PTL). Power transmission lines are a critical element of the energy infrastructure, and their reliable operation directly affects economic stability and safety. Traditional monitoring methods, such as visual inspections and mechanical devices, have long remained the main control tools, but their limited accuracy, high dependence on the human factor and the inability to promptly detect hidden defects make them less effective in the face of increasing loads on power systems. Modern technologies, including unmanned aerial vehicles (UAVs), the Internet of Things (IoT), automated monitoring systems and digital twins, offer fundamentally new opportunities for monitoring the condition of PTLs. They provide high diagnostic accuracy, continuous data collection in real time, reduced operating costs and increased personnel safety. The article presents a classification of both traditional and modern methods, as well as a comparative analysis of their key parameters: accuracy, response speed, cost, safety and impact on operation. The results of the study demonstrate that modern technologies outperform traditional approaches in all the criteria considered. In particular, the use of IoT and UAVs allows minimizing the human factor, reducing inspection time and increasing data detail. Digital twin systems make it possible to predict possible accidents and optimize scheduled maintenance. However, successful implementation of innovative solutions requires additional investment, personnel training and integration with existing management systems. The conclusion is made about the strategic importance of switching to modern power transmission line monitoring technologies to improve the reliability and sustainability of the energy infrastructure. Despite high initial costs, their long-term benefits, including reduced accidents, resource savings and increased safety, fully justify the investment. The authors emphasize the need for further development of digital technologies in the energy sector to ensure stable and efficient operation of power grids

  Abstract ▼

  An integrative model has been developed that combines calendar planning methods with software functionality (Excel, MS Project) for multi-level project optimization. Central focus is placed on three complementary methodologies: the Gantt chart, network diagram, and critical path analysis, which form the conceptual foundation for effective coordination of project processes. The study details the algorithm for creating a Gantt chart, which visualizes timeframes and task sequences, with emphasis on the functional capabilities of specialized software solutions, including Microsoft Project and Excel, enabling automated construction and adjustment of schedules. Further, the principles of constructing a network diagram, interpreted as a directed graph with edges (tasks) and vertices (events), are elaborated. This approach allows for identifying logical dependencies between project stages and determining the critical path – a sequence of operations with zero time reserves, defining the project’s minimum duration. Practical illustrations of critical path calculations are supported by examples demonstrating its role in optimizing time resources. A key aspect of the study is the analysis of time reserves, aimed at minimizing deadline risks through rational resource reallocation. The methodological framework is supplemented by visualization tools: resource requirement graphs and resource load diagrams, ensuring operational control over material and personnel assets across all project phases. The final element of the planning system is the calendar plan, which structures data on work titles, chronological intervals, and resource intensity. This document serves as an integrative foundation for synchronizing operational activities, ensuring adherence to established deadlines
