PQ and Harmonic Assessment Issues on Low-Cost Smart Metering Platforms: A Case Study

2020

This paper presents a feasibility study on how to implement power quality (PQ) metrics in a low-cost smart metering platform. The study is aimed at verifying the possibility of implementing PQ monitoring in distribution networks without replacing existing smart metering devices or adding new modules for PQ measurements, thus zeroing the installation costs. To this aim, an electronic board, currently used for remote energy metering, was chosen as a case study, specifically the STCOMET platform. Starting from the specifications of this device, the possibility of implementing power quality metrics is investigated in order to verify if compliance with standard requirements for PQ instruments ca…

Impact of non-programmable distributed generation in an islanded microgrid: the case study of Ustica

2022

The paper presents a systematic analysis of nonprogrammable distributed generation impact in an islanded microgrid Different issues have been analyzed, with a special focus on the most significant ones in a small islanded network. To this aim, the case study of Ustica island was considered A digital twin of the MV network was developed starting from the network topology data and the power measurement acquired in each secondary substation. Simulations were then performed in the hypothesis of a large increment of distributed generation installation into the network. A discussion is then reported on which are the main technical issues to be faced in the considered case study.

A modular neutron irradiator based on 241Am-Be neutron sources

2010

Neutron irradiator facilities with 241Am-Be sources are worldwide used in order to perform neutron activation analysis (NAA), to investigate materials in different research areas or to test and calibrate neutron detectors and environmental or personal dosemeters. The use of a neutron irradiator is advantageous because of its very stable neutron flux, even it is many orders of magnitude lower than the one of a nuclear reactor or a particle accelerator. Most of irradiators are realized with neutron sources located at fixed positions and accordingly the characteristics of neutron spectrum previously assessed do not change. Therefore, an interesting choice is to have a modular facility, capable…

Compensation of Nonlinearity of Voltage and Current Instrument Transformers

2019

This paper aims at characterizing and improving the metrological performances of current and voltage instrument transformers (CTs and VTs) in harmonic measurements in the power system. A theoretical analysis is carried out to demonstrate that, due to the iron core nonlinearity, CT and VT output signal is distorted even when the input signal is a pure sine wave. Starting from this analysis, a new method for CT and VT characterization and compensation is proposed. In a first step, they are characterized in sinusoidal conditions and the harmonic phasors of the distorted output are measured; in the second step, these phasors are used to compensate the harmonic phasors measured in normal operati…

Le famiglie di soggetti autistici, le giovani donne affette da disturbi del comportamento alimentare, gli alcolisti, i tossicodipendenti, i giovani a rischio devianza dei quartieri degradati e coloro che usufruiscono delle misure alternative alla detenzione sono alcune degli attori che, venendo a far parte di nuovi aggregati identitari, mappano i contesti locali in spazi simbolici, in localitè, società urbane incomplete che rinviano a nuove questioni sociali e a differenti derive cui il welfare locale cerca di rispondere. Nel tentativo di esplicitare il groviglio fra solidarietà e povertà, capitalizzazione dei legami e inadeguatezza della rete, progettualità sociale e limiti organizzativi, …
