Considerazioni Critiche e di Prospettiva sulle Misure Provvisorie della Corte Internazionale Di Giustizia nel Caso Gambia c. Myanmar
2021
L’ordinanza adottata dalla Corte internazionale di giustizia il 23 gennaio 2020, in risposta alla richiesta di misure provvisorie presentata nell’ambito della controversia Gambia c. Myanmar e relativa alla presunta violazione della Convenzione per la prevenzione e la repressione del delitto di genocidio, contiene diversi spunti interessanti che, probabilmente, incideranno sulla prosecuzione del giudizio. Il presente scritto esamina le questioni procedurali e sostanziali che emergono dalla medesima. Quanto agli aspetti procedurali, ci si soffermerà, in particolare, sul locus standi dinnanzi alla Corte di uno Stato non direttamente leso da violazioni di obblighi erga omnes partes e sulle pros…
Coupling circuit for power line communications
2013
A coupling interface couples a transceiver to one or more capacitive voltage dividers of a power transmission system. The coupling interface includes a first signal path including an adjustable inductance configured to form a resonance circuit with a capacitance associated with the one or more capacitive voltage dividers. The coupling interface may include a second signal path including an adjustable inductance configured to form a resonance circuit with the capacitance associated with the one or more capacitive voltage dividers.
An Innovative Coupling Solution for Power Line Communication in MV Electrical Networks
2019
One of the main problems in the diffusion of power line communication (PLC) in medium voltage (MV) networks is the need of a dedicated PLC coupler to be installed all over the network. To avoid this problem, the authors have studied, prototyped and patented an innovative PLC coupling solution which uses electrical elements embedded in most of the switchgears already installed in MV networks, i.e. the capacitive dividers of the voltage detecting systems (VDS). The new solution prototype is described in this paper, highlighting the advantages in terms of a significant reduction of both direct costs of equipment and infrastructures and indirect costs of installation and service interruption. T…
Simulation of a Power Line Communication System in Medium and Low Voltage Distribution Networks
2011
The aim of the paper is to study the influence of the power transformer on signal transmission in the case of a power line communication (PLC) system in a overhead Medium Voltage (MV) power network. A model of the PLC system was carried out by means of the Simulink® software. A distributed parameter MV overhead line, two power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver were included in the model. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.
Measurement and communication interfaces for distributed generation in smart grids
2013
The aim of this work is to perform a feasibility study on the measurement and communication strategies for the development of a new generation of interface devices for distributed generators and their integration on smart grids. The communication system can use one or more technologies, at the various levels, creating a low cost network infrastructure, in the framework of a SCADA (Supervisory Control and Data Acquisition) architecture. As regards the measurements, the attention is focused on the anti-islanding protection, based on a hybrid solution, which makes use of local measurements and communications with the grid, at both MV and LV level by employing the PLC technology. Some simulatio…
An interface protection system with power line communication for distributed generators remote control
2014
The aim of this work is to present a narrow band power line communication (NB-PLC) interface protection system (IPS) for distributed generators (DGs); it has been developed according to the current standard CEI 0-21 and the requirements for smart grid applications. For such applications, the new IPSs have to implement new intelligent functions such as remote monitoring and control of DGs and Energy Storage Systems (ESSs) inverters, not only in terms of disconnection but also of voltage regulation and power modulation by the utility control. The main feature of the developed IPS is the ability to interact with both the grid and the DG's and ESS's inverters. In fact, it can communicate with t…
Innovative Solutions for the Integration of Renewable Energies on Tunisian and Sicilian Electrical Grids
2022
The rapid spread of distributed generation from renewable energy sources, combined with their unpredictable behavior, requires the continuous monitoring and control by the Distribution System Operator, in order to guarantee the stability and efficiency of the distribution network. Thus, in this paper a new measurement and communication architecture is proposed, which foresees the use of innovative devices and different technology-oriented solutions, even redundant ones, which allows the transition from passive to active electricity distribution network, with minimal structural changes. The architecture has been developed in the framework of the SInERT project (Italy-Tunisia cross-border coo…
