The Powerline Communications (PLC) technology allows data transmission through electrical wires. Thus the electrical wiring will represent a data transmission channel conformable to the physical layer of the open system interconnection (OSI) model. In this work, the specifications of the Iraqi electrical network were used to model a high-voltage transmission line using a transmission (ABCD) matrix and use it as a communication channel for transmitting data within a narrow band . The transfer function of the suggested model was derived and its performance analysis was performed to evaluate the Line length effect, load impedance Z L and the source impedance Z S on the channel frequency response. This analysis was done with the help of Matlab16a simulator program. Index Terms-High voltage, Iraqi power network, transmission line model.According to the Iraqi power grid, a high voltage power line (132 kV) has been modeled as a communication channel for narrowband (28 -500 kHz) data transmission [8]. A signal from PLC travels from the transmitter, coupling devices over the power line to the receiver. A similar path is provided for the bidirectional path. Three different parts of the PLC system are shown in Fig. These parts are terminating system, coupling device and transmission line [9]. The terminating system contains a transmitter, receiver, and

“…Understanding the precise causes of power line failures enables more effective control of the whole network since the high dependability of power transmission lines is one of the key factors that ensures network stability over time [23]. Given these details, it is desirable to model the transmission power lines, which, in addition to offering the chance to confirm any fault occurrence, offer extra significant advantages.…”

The work proposes an original method for modeling and simulating the triggering of 110 kV interconnection power lines in case of common faults, such as transient or persistent faults. Urban and industrial areas, surrounding urban areas, require a high energy consumption that is being supplied through 110 kV overhead power lines, responsible for distributing power to the industrial and domestic consumers. High voltage distribution power lines are most prone to failure, due to their exposure, affecting a large number of consumers if a fault occurs. Faults of power lines in service certify that currently there is no perfectly controllable operation mode in terms of load rating, environmental factors, insulation resistance, or mechanical resistance, which would allow total avoidance of faults, it is only possible to reduce the impact they have on the network as a whole. Mathematical models have been developed to determine the experimental voltage and current responses describing the fault propagation, expressed as a 7th-degree polynomial curve, as a second-order transfer function or as the Gaussian model type. By comparing these mathematical models, the most probable answers that can lead to the development of a control structure for rapid identification of a fault were obtained, with the possibility of triggering the line protection relay. In the final part of the manuscript, the viability of applying artificial intelligence techniques, for the approached fault management application, is proven. The developed control structure evaluates the nature of the fault and determines a faster reaction of the line protection causing an increase in the performance of the distribution service.
