“…The images allow users to check electrical grid assets and components, zoom in for more details, and view the location in 360°. As this platform is web-based, and the data are stored in a global company repository at the cloud, everyone in the company can access and benefit from it [18].…”

“…In this way, the team that performs the trimming of trees can generate their prioritization by distancing them from the network and be more efficient in the execution of these cuts. The evolution of this point cloud over time can allow predictive maintenance software to predict when a particular tree will be close to the network, thus allowing for trimming planning with current and near future needs [18]. Whereas the point cloud is a great technology for scanning visible and touchable assets, there are other kinds of grid elements that are not visible.…”

“…It can be achieved with a coupling device in the smartphone. That solution is commercially available and brings good results [31].The use of drones can also serve the same purpose in the overhead grid and underground vaults [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Considering a technical specification for thermal cameras usage in the electrical system, it is recommended to consider a device that supports −20 ºC to 330 ºC and has the thermal sensibility of less than 150 mK.…”

“…[17] shows how thermographic devices can facilitate the early detection of faults in the electrical distribution network before they can cause interruption of operation and cause damage and incidents due to short circuits and fires. The study in [18] proposes the digitalization and 3D modeling of the power distribution network through a Mobile Mapping System (MMS) with different technologies that compound the NDT©. The case study presented in [19] shows a practical example of the usage of the GPR in the underground distribution grid in the city of São Paulo, Brazil.…”

“…To carry out the foundation layer, some different technologies are used. One of them is a mobile mapping system (MMS) [18], whose main objective is to build the basis of the DT model of the power grid. The MMS consists of the creation of a 3D point cloud model in conjunction with the capture of visual and thermographic images of the network.…”

Through the transformation that the electrical sector has been passing by, improvements in asset management and the guarantee of sustainable and quality services have become essential aspects for power companies. Thus, the digitalization of energy utilities presents itself as an important and crucial process. A concept that involves a variety of innovative trends is the digital twin. It consists of a 3D virtual replica of existing physical objects and real-time monitoring of certain measures. By developing a digital twin in the electrical power grid, a virtual replica of the network is obtained providing network virtual maps, 3D asset models, dynamic and real-time data of grid assets, and IoT sensing. All these data can feed a platform where AI-based models and advanced field operation technologies and solutions will be applied. With a Network Digital Twin©development, applications involving on-field activities can be improved through augmented reality (AR) and virtual reality (VR) to enhance workforce operations. This paper discusses the best practices for the development of a digital twin for the electrical power sector. These practices were found during the development of a project carried out by Enel Distribuição São Paulo, applying a living lab concept in the densest region of Brazil. The results of this paper present 3D images captured with specialized tools, and how they influence the workforce activities of human interface operation. Furthermore, financial and operational returns are presented through a cost–benefit analysis for each relevant aspect.

Application of Digital Twin in Medium-Voltage Overhead Distribution Network Inspection

et al. 2023

View full text Add to dashboard Cite

The paper is devoted to the digital transformation of the core engineering maintenance processes involved in medium-voltage overhead distribution network infrastructure inspection. The study presents an analysis of digital twin utilization for inspection of the infrastructure of medium-voltage overhead distribution networks. At present, the infrastructure monitoring process is still manual, and its automatization is a challenging task due to the large distances between and small dimensions of the elements involved. The proposed digital twin is employed for 3D infrastructure modeling and complex analysis based on photogrammetry and aerial scanning data processing methods. The paper describes practical use cases for these data-driven methods for specific infrastructure management processes, e.g., scheduled inspection processes, including geometrical parameter measurements and visual infrastructure element defect identification, unplanned inspection processes (state of emergency, post-storm, etc.), and vegetation management processes. The proposed method allows operations to be performed remotely without physical presence in the field. At the same time, data-driven solutions provide objective results and potential automation via machine learning algorithms, which are more profitable economically. As the proposed method allows processes to be performed remotely, these data-driven solutions offer cost-effective results for automation. The digital twin concept is applied to the Latvian medium-voltage overhead distribution network with the support of the Latvian distribution system operator “Sadales tīkls” JSC.
