Design and Simulation of Fast Discharge Units (FDUs) for Toroidal Field Coils of Divertor Tokamak Test (DTT)
2023
Questa tesi riassume il lavoro svolto durante il triennio di dottorato nel periodo compreso tra il 2019 e il 2022. Come è ben noto nella comunità scientifica, l'ambiziosissimo progetto di fusione nucleare ha richiesto e richiede notevoli risorse ed investimenti; La tabella di marcia per la generazione di energia da fusione nucleare su larga scala comprende missioni impegnative. I progetti ITER e DEMO, essendo progetti internazionali, richiedono la collaborazione (sia dal punto di vista economico che tecnico) di diversi Paesi a livello europeo ed extraeuropeo; per questo motivo i vari aspetti tecnologici, che verranno poi implementati e applicati nei reattori a fusione finali, vengono prima …
A New Protection Strategy for Electrical Distribution Systems
2010
In this paper, the authors propose a new protection strategy for electrical Medium Voltage distribution networks, based on a distributed intelligence system composed of a central unit and of many local processing units. The distributed intelligence system can precisely identify and locate faults in suitably limited times. Each local processing unit is composed of a data acquisition system and a data analysis system. The first allows the accurate reconstruction of the fundamental using only 1.5 cycles of under fault transient electrical quantities. The second performs suitably precise on-line fault diagnosis based on the data provided by the data acquisition module. The data acquisition algo…
Guidelines and Conceptual Design of the Grounding System of the DTT Experimental Facility
2022
The Divertor Tokamak Test (DTT) is an experimental nuclear fusion reactor currently under construction at the ENEA research center in Frascati and whose first plasma is expected in 2025. The present article shows the conceptual philosophy and the guidelines behind the design of the grounding system of the DTT. The article focuses on the main target of the grounding system and on the main technical standards to refer to for the design.
Dynamic thermal rating for overhead lines: Self-adaptive protection device
2013
The increase in the consumption of electricity, the stringent environmental restrictions and the need to keep costs, make ever more meaningful the need for a flexible operation of existing overhead lines. This paper studies the possibility to use a dynamic thermal rating for overhead line starting from the analysis of the mathematical model and the ability of the latter to reflect the temperature of an overhead conductor in different ambient condition; then it simulates the thermal behaviour of a conductor both in steady state and dynamic one. Finally the paper shows a method for a self-adaptive thermal protection system.
ARC FAULT DETECTION EQUIPMENT AND METHOD USING LOW FREQUENCY HARMONIC CURRENT ANALYSIS
2012
An arc fault detection circuit includes a current sensing circuit coupled to a line conductor carrying a current. The current sensing circuit operates to sense current and output data indicative of the sensed current. A processing circuit implements a frequency transform algorithm to transform the output data to frequency data in a low frequency range and with a high spectral resolution where a minimum short time observation window is concerned. The processing circuit identifies an arc fault condition on the line conductor by identifying differences in said frequency data between at least two subsequent observation windows and identifying characteristics which exceed thresholds.
Green calims, green washing and consumer protection in European Union
2021
The purpose of this paper is to offer some reflection on the importance of reliable green claims to encourage sustainable production. The role of market is fundamental. Businesses and consumers are both involved in achieving environmental protection objectives. There is the real risk of the phenomenon of so-called green washing or misleading marketing. The problem arises of verifying the reliability of green claims to prevent competitive elements from become distorting factors of competition.

La tutela del contraente debole nella platform economy dopo il Regolamento UE 2019/1150 e la Direttiva UE 2019/2161 (c.d. Omnibus)
2020
The article summarise the main legal issue related to the protection of users of online service providers in the light of Reg. EU 2019/1150 and Dir. EU 2019/2161
La categoria del rimedio nel sistema del diritto civile
2018
The essay analyzes the category of remedy by reviewing the main conceptions which have emerged so far. Useful elements are drawn from the critical analysis of the most articulated these, providing a notion of remedy able to highlight its essential feauteres, its applicative potential and its limits. To this end, the essay deals with some emblematic cases in which there has been too loose a use of the category of remedy. The end of the study illustrates a notion of remedy that appears more rigorous and more in keeping with the characteristics if the iurisdictio.
La disciplina giuridica delle piattaforme online per la ristorazione
2022
The paper investigates the legal issues concerning online platform for restaurants. A coherent regulatory framework of these platforms is proposed, considering the P2B and B2C relationships involved in their activities, with a focus on the protection of food choices and personal data entered by users. While for the P2B issues the European legislation lay down by Reg. EU n. 1150/2019 and the previous Dir. 2000/31/EC on electronic commerce is involved; the B2C issues are discussed considering the regulation on unfair commercial practices provided by Dir. n. 2005/29/EC and, specifically, Reg. EU n. 1169/2011 on food information. As regards the privacy issues of the platform customers, the GDPR…
