Feature Information

There are a large number of insulators on the transmission line, and insulator damage will have a major impact on power supply security. Image-based segmentation of the insulators in the power transmission lines is a premise and also a critical task for power line inspection. In this paper, a modified conditional generative adversarial network for insulator pixel-level segmentation is proposed. The generator is reconstructed by encoder-decoder layers with asymmetric convolution kernel which can simplify the network complexity and extract more kinds of feature information. The discriminator is composed of a fully convolutional network based on patchGAN and learns the loss to train the generator. It is verified in experiments that the proposed method has better performances on mIoU and computational efficiency than Pix2pix, SegNet, and other state-of-the-art networks.

The Mathematical Model

This paper investigates a mathematical model of one elements of the power supply system - power transmission lines. The type of models depends on the initial simplifications, which in turn are determined by the complexity of the physics of processes. The task of improving the accuracy of modeling of emergency processes in the power system is due to the significant complexity of modern power systems and their equipment, high-speed relay protection, automation of emergency management and the introduction of higher-speed switching equipment. One of the reasons for a significant number of serious emergencies in the system is the lack of complete and reliable information for modeling modes in the design and operation of power systems. The development of a mathematical model of a three-phase power line, which provides adequate reflection of both normal and emergency processes, is relevant. The advanced mathematical model of power transmission lines allows to investigate various operational modes of electric networks. The improved mathematical model of the power transmission line reflects all the features of physical processes at state modes and transient process and provides sufficient accuracy of the results. The type of mathematical model of power transmission lines depends on the accepted simplifications, depending on the task of research. The purpose of this work is to analyze the mathematical model of the power transmission line to study the modes of operation of the power supply system, with the possibility of its application to take into account all the design features of overhead and cable power lines. The mathematical model of the power line for the study of the modes of operation of the power supply system is analyzed. It is used to take into account the design features of overhead and cable power lines, skin effect.

Using renewable energy off-grid power supply and choosing the right equipment that meets the operating conditions in the Arctic can provide companies with reliable power sources for producing gas at facilities located in remote areas and will reduce capital and operating costs associated with the construction of power transmission lines. For more than 15 years, a remote control system powered by renewable energy has been used in parallel with power transmission lines by Gazprom to operate its multiwell pads in Russia’s Far North, which validates the relevance of this study. The subject of the study is a group of gas condensate wells that consists of four multiwell pads operated by Wintershall Russland GmbH. The article discusses a stand-alone renewable-based power system as an option for powering remote oil and gas production facilities. The procedures used in the study include calculating such parameters as power output and power consumption, choosing equipment, describing the design features of a power supply system for a multiwell pad, conducting an economic assessment of the project, comparing different power supply options, analyzing project risks, and developing measures to mitigate these risks.

Inspection Tasks

Insulator detection is one of the most significant issues in high-voltage transmission line inspection using unmanned aerial vehicles (UAVs) and has attracted attention from researchers all over the world. The state-of-the-art models in object detection perform well in insulator detection, but the precision is limited by the scale of the dataset and parameters. Recently, the Generative Adversarial Network (GAN) was found to offer excellent image generation. Therefore, we propose a novel model called InsulatorGAN based on using conditional GANs to detect insulators in transmission lines. However, due to the fixed categories in datasets such as ImageNet and Pascal VOC, the generated insulator images are of a low resolution and are not sufficiently realistic. To solve these problems, we established an insulator dataset called InsuGenSet for model training. InsulatorGAN can generate high-resolution, realistic-looking insulator-detection images that can be used for data expansion. Moreover, InsulatorGAN can be easily adapted to other power equipment inspection tasks and scenarios using one generator and multiple discriminators. To give the generated images richer details, we also introduced a penalty mechanism based on a Monte Carlo search in InsulatorGAN. In addition, we proposed a multi-scale discriminator structure based on a multi-task learning mechanism to improve the quality of the generated images. Finally, experiments on the InsuGenSet and CPLID datasets demonstrated that our model outperforms existing state-of-the-art models by advancing both the resolution and quality of the generated images as well as the position of the detection box in the images.

One of the major threats to the safe and normal operation of the power transmission lines is the external force or intrusion incurred by construction trucks. Especially for the urban area, construction of truck cranes is increasingly becoming a leading cause to the damages of power transmission lines. However, the conventional monitoring method for protecting power transmission lines is to conduct a routine inspection or patrol on the transmission line network periodically, which is time-consuming and laborious. In this paper we propose a video surveillance system for automatic tracking the dangerous strength such as construction cranes. The criterion of context formation aims to detect the jib of crane and compute its extension angle. Once the crane is parked over a certain period of time, or the jib extension angle exceeds predefined thresholds, warning messages will be sent to power line supervisors. The experiments show that the system is able to achieve automatic detection of truck cranes and protect transmission lines from their careless constructions.

The integration of different stakeholders’ perspectives when planning large-scale infrastructure projects such as power transmission lines is becoming increasingly important in the public debate. Partly conflicting interests of stakeholders should be taken into account in order to allow for best possible routing of new lines. Particularly when transmission lines which are bridging large distances are considered, externalities within this complex setting include social, ecological, economical and technical dimensions. An optimal routing of lines may help address different issues, such as public resistance. Models for the investigation of these large-area impacts for optimal route formation often only cover small regions or lack the georeferenced data necessary to quantify different criteria. We develop an open-source approach which allows for transparent and replicable route determination, tracing, and assessment covering the whole of Europe. Therefore, we provide several friction layers with high spatial resolution. Each layer represents a criterion affecting the routing of a power line. Together with the start and end point of a construction project, this allows for creating accumulated cost rasters for various relationships between the weightings of the perspectives which are relevant during line infrastructure routing processes. The present work explains the underlying methods of data collection, processing, and algorithms of data preparation, route generation, and assessment. Subsequently, this approach is verified with two case studies of HVDC transmission lines which are currently in the planning stages. All processed datasets and applied scripts described in this paper are open-access and made publicly available. Hence, this should support the current project routing debate by providing more transparency and by improving stakeholder involvement.

Sectionalizing 0.4 kV power transmission lines (PTL) improves power supply reliability and reduces electricity undersupply through the prevention of energy disconnection of consumers in the event of a short circuit in the power line behind the sectionalizing unit (SU). This research examines the impact of sectionalizing on power supply reliability and reviews the literature on sectionalizing unit allocation strategies in electrical networks. This paper describes the experience of the use of sectionalizing units with listing strengths and weaknesses of adopted technical solutions and describes the new structure of sectionalizing units. A new methodology is proposed, whereby there are two criteria for allocating SU in 0.4 kV power transmission lines. The first criterion is the sensitivity limits against single-phase short circuits used for calculating the maximum distance at which SU can be installed. The second criterion is power supply reliability improvement, evaluating the cost-effectiveness of installing sectionalizing equipment by reducing power supply outage time. The established methodology was put to the test on an actual electrical system (Mezenka village, Orel area, Russia), which demonstrated that the installation of a sectionalizing unit paid off.

Abstract The fauna and structure of herbdwelling spider assemblages in mesophitic meadow under the high voltage power line near Irliava village (Uzhhorod District, Transcarpathian Region) were analyzed on the material collected by sweep netting. Th e counts were held at five sampling sites: 1) under the wires; 2) at a distance of 50 m; 3) 100 m; 4) 150 m; 5) 200 m. In total, 41 spider species of 14 families were collected. Erigonoplus globipes (L. Koch, 1872) and Hylyphantes nigritus (Simon, 1881) were recorded in the Carpathians for the first time. Th e reduction of total number and species richness of spiders was registered as the approaching to the high voltage power line. Except single finds, no species avoided the wire nearest sites (0-50 m). Abundance of most spider families (except Araneidae) was not significantly influenced by distance from the high voltage power line.
