Busbar distribution systems are highly preferred to carry electrical energy as a part of the low-voltage grid in order to meet power requirements, especially in industrial areas. From the perspective of broadband power line communication possibilities in the smart grid concept, there is a need to know for high-frequency characteristics of busbars. This paper investigates the influences of line length...
In recent years, design and service evolution in electric distribution networks are mainly guided by the increasing in the customer consumption and the emergence of new sources and loads such as renewable energy, electric and hybrids vehicles. The lack of control over these new constraints in the future may lead to technical and financial problems. Therefore, establishing a supervisory strategy offering...
Nowadays, Power Line Communication is becoming an attractive solution to deliver broadband services to indoor and outdoor environment because this technology allows the use of the existing infrastructure. The knowledge of the channel characteristics is very important. A perfect real multipath model is very difficult to be found out because depends on cable models and topology but an accuracy approach...
Impedance modeling for low voltage distribution network has important applications in power line communication and smart home constructions. Attribute to the topologies and loads connection, impedances of low voltage power line and loads are various and complicate. To obtain impedance characteristics of resident community distribution network, impedances characteristics with time and frequency are...
This work propose a power line (PL) channel identification methodology based on the impulse response theory using low cost digital standard technology. In order to achieve efficient broadband communications over PL channels in Small-Office Home-Office environments, it is necessary to improve the indoor PL channel models. Then the proposed methodology and model makes practical to generate a large database...
The complicated channel characteristics are the main obstacles for the development of 10 kV power line communication. Based on the two-port networks, the ABCD-parameters matrix channel model is established, in which the propagation rules of basic unit accord with the transmission line theory. The working attenuation of the whole network is analyzed, which reveals the causes of frequency selective...
In this paper we investigated power line simulation method using PLCS3000 which can duplicate the real power line characteristics efficiently. It was confirmed that the influence on transmission characteristics of PLC when using SPD.
The aim of this paper is to illustrate the development of a theoretical and experimental study on the characterization of medium voltage (MV) cables in the frequency range 25-200 kHz. Two transmission line configurations, line-ground and line-line, were considered in order to evaluate the main parameters, such as the characteristic impedance and the attenuation constant alpha. A simplified model of...
Problems that power line communication (PLC) technology is faced to are different classes and types of conductors used for construction of medium and low voltage networks (non-insulated conductors, underground cables, aerial bundled conductors, semi-insulated conductors). These problems complicate unified implementation and installation of PLC equipment. Characteristics of respectable types of power...
Electrical energy consumers are demanding better customer service, higher power quality, higher energy measurement accuracy and more timely data. Utility companies all over the world are being forced to find solutions giving greater information on the population's power consumption. The automatic meter reading system (AMR) is one of the ways in which utilities are go-getting to achieve these goals...
