“…At the same time, the active resistance linearly depends on the temperature of the wires, the overheating of which depends on the current flowing through them. In addition, in previously published works [19][20][21] it is shown that corona losses depend on stresses in the power of 4-10. In addition, there is a reactive effect of the corona [20].…”

“…In addition, in previously published works [19][20][21] it is shown that corona losses depend on stresses in the power of 4-10. In addition, there is a reactive effect of the corona [20]. Therefore, when using the objective function COR(V,W) as components, the weighting factors were taken equal to zero at the correlation coefficients between: R0 and 1 2 + 2 2 , G0 and 1 2 + 2 2 , B0 and 1 2 + 2 2 .…”

This work is devoted to the research of the real-time estimation of 500 kV power transmission lines parameters with PMU based on the solution of the optimization problem of minimizing the root-mean-square deviations of the specific line parameters or the sum of the modules of the correlation coefficients between the specific parameters and the sum of the squares of the voltages or currents measured at the ends of the line. Independent optimization variables are the correction factors of the measuring systems of currents and voltages. Based on an artificially simulated PMU dataset with specified Gaussian noise and systematic errors, it is shown that the use of correlation coefficients in the objective function is more effective than standard deviations. All 5 estimated coefficients turned out to be closer to the reference values. The results of calculations are obtained from the data of real PMUs for an operating 500 kV line with a length of 504.6 km. The deviation of the specific capacitive conductivity from the nominal value is 0.13%, compared with - 0.29% when using the sum of squares of deviations as an objective function.

“…This shows the air parameters, for example, temperature, pressure, wind speed, dampness, and so on., have the huge impact in the age of particles in the region of the HVDC transmission lines. Enock Chambile, et.al [2] reviewed a study on the direct non-generation greenhouse gas emissions in the construction and operation of the national electrical power transmission and distribution (T and D) system was conducted in order to understand its impact on climate change. The results revealed that the impact of the distance of T and D lines to the greenhouse gas emissions, due to vegetation removal, is insignificant.…”

Depending upon material science law and guidelines, the factors of overhead lines in network, electric and meteorological data recorded the essential relationships with the corona losses and the states of climate are normally spotted. Corona losses occurred to be characterized just by weighting components for particular states of climate of average twelve Bulgarian territories showing components of complete transmission lattice. A determining unit imply on a measurable procedure worried on an hourly premise corona shortfall is inspected and proposed to have the option to decrease the lopsided characteristics costs. This casing work includes a proposed model of learning for limiting the corona losses. The deficiencies of suggested approach lessen in each situation since it speaks to an effective learning adaptation and at the hour of testing it productively figure heat/temperature giving an extraordinary effect to fundamentally losses decrease. The fundamental purpose for the improvement of learning approach is that the learning approach sums up the information however expectation approach utilizes dynamic choice and disregards past information execution.

“…Recent PLC now offers high-speed data transmission and also economical as it makes use of the communication system already present and the cost mainly associated is only with the terminal equipment. More about this subject has been found in references [3][4][5][6]. Analog PLC (aPLC) is commonly used for transmission of voice and low data rate.…”

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
