Powerline communications transfer high-speed information in the power grid equipment which has obtained great success. In order to make transformation rate higher, the bandwidth is 1–30MHz. Broadband power line as the communication link whose channel characteristics have very important effect on the communication quality. This paper analyses these characteristics of impedance, noise and the signal's...
with becoming a complex structure of the electricity network, smart grid architecture and technologies became very important. The most widespread smart grid technology is PLC for managing and controlling the devices in the electricity network. To design a reliable PLC device is not a straightforward issue, especially channel characteristics must be known such as impedance, noise level and attenuation...
Recent advances in power line communication technology has created a large demand for access to network services inside premises. Power line communication has emerged as a strong candidate under such circumstances. Quality of service in power line communication relies heavily on characterization of the medium. This paper analyzes the channel characteristics of power line. A transmission line model...
While indoor wireless mobile networks require quite a few access points, the electric power distribution network inside a building is pervasive. A power cable is leaky and lossy at higher frequencies, but it can be used as a transmission line and as an antenna for extending last few metres or circumventing blind spots and dead corners of a wireless link between a mobile device and an access point...
Broadband power line communication (BPLC) systems use the existing electrical cables to transfer high-frequency communication signals. Its aim is to provide customers with a high-speed access to communication services such as Internet. The traditional methods which used to solve the parameters of the multi-conductor transmission line with the electromagnetic theory are very complex. By introducing...
The power line communications has been applied as a data transfer method in both public electricity distribution networks and indoor distribution networks. The industrial low voltage distribution network may be utilized as a communication channel to data transfer required by the on-line condition monitoring of electric motors. The advantage of using power-line data transfer is that it does not require...
Power line communications (PLC) technologies rely on the power grid for data transmission. Since the communications channel is already deployed, this communication alternative is specially interesting for the power grid owner, i.e., the electrical utility (EU). Focusing on the MV distribution network, located after the last step-down electrical substation, with typical levels from 6 to 25 kV, feeds...
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...
