ARERA (the Italian Regulatory Authority) has also set up a technical round table with TSOs and DSOs to increase the resilience of electrical infrastructures in the face of increasingly frequent severe meteorological events.<\/p>\n<p>In particular, during 2020 the following issues were addressed:<\/p>\n<ul>\n<li>Meteorological phenomena with snow and ice overloads on overhead power lines: the activity involved the creation of new coatings and the study of devices to mitigate the phenomenon. Characterization and verification of coating performance was carried out in the laboratory and on field installations. Modeling and testing of the mechanical properties of wet snow was also addressed.<\/li>\n<li>Contaminant accumulation phenomena on insulators: Activities included the creation of a new national map of insulator contamination levels with optimal interpolation algorithms, the improvement of the critical condition prediction and warning system, and the study of new coatings to improve insulator sealing.<\/li>\n<\/ul>\n<p>Heat waves and lack of rain: in this context, it is planned to develop systems for diagnosing, monitoring and predicting the condition of MV cable grids. The activity developed includes the completion of aging cycles of joints in conditions of soil drying and the creation of a new test set-up with the possibility of simulating rain conditions.<\/p>\n<ul>\n<li>The activity also included the development of the hardware components of a new open and integrated diagnostic tool for the detection of partial discharges.<\/li>\n<li>Resilience and fragility of electrical substations against earthquakes and floods: measurement campaigns have been carried out to evaluate the aspects of local seismic amplification in areas with the presence of electrical system elements, and the analysis of analytical and empirical methods for the definition of fragility curves has begun, with the definition of a specific database for such curves.<\/li>\n<li>Superconducting components and devices for AC and DC grids: numerical simulation activities of the behavior of Superconducting Fault Current Limiters (SFCLs) in AC electrical grids for different types of HTS (High Temperature Superconductor) tape and stress and strain measurements of superconducting tapes using strain gauges at cryogenic temperatures were carried out. Activities to compare the thermodynamic properties of cryogenic fluids using different s-waves were completed and further data was collected on the design criticalities that most affect HTS equipment.<\/li>\n<li>Modeling and diagnosis of aging phenomena in solid dielectric insulations: A new numerical technique has been developed to simulate real components that also contain semiconducting layers. The partial discharge triggering mechanism was modeled in more detail and the ion-polyethylene interaction contributing to treeing propagation was modeled. A new prototype of an electro-optical partial discharge measurement system was also completed.<\/li>\n<li>Advanced diagnostics and sensors for transformers (also in the presence of new insulating fluids): the possibility of using polymer interfaces for the analysis of laboratory 2-Fal standards was verified. The circuit configuration was defined to reproduce an accelerated degradation of the solid insulation system. With regard to the vibrational analysis of transformers, the results have confirmed the high reliability of the Support Vector Machine (SVM) classifier on the single measurement position of the housing.<\/li>\n<\/ul>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":166061,"id":166061,"title":"20011031","filename":"20011031.pdf","filesize":1733484,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2022\/05\/20011031.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/rapporto-di-sintesi-2020-del-progetto-1-4-componenti-e-materiali-per-la-sicurezza-e-la-resilienza\/attachment\/20011031\/","alt":"","author":"93","description":"","caption":"","name":"20011031","status":"inherit","uploaded_to":166060,"date":"2022-05-10 07:49:17","modified":"2022-05-10 07:49:17","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2020-12-30","autori":"G.
