Improving the passive capacity of the electric power transmission lines is one of the main challenges for electric grid operators, in order to meet the growing demand for electrical energy. Especially when these networks reach their critical thermal limits as a result of the growth of loads or the occurrence of permanent malfunctions, and their inability to meet the growing growth of electrical loads, and for this purpose researchers resort to searching for technical solutions that enable them to transfer a greater amount of electrical capacity across the network itself.
In this research, we will study the flow of electrical power in the 230Kv high voltage transmission network from Baniyas to Lattakia, after the exit of the Zayzoun power station, and its relationship to the transmission line impedance changes on the one hand, and the power transmission angle on the other hand, and search for solutions to improve its value, and determine the best values for each Of inductive reactance and power transmission angle of the network. Taking into consideration the national resistance of the transmission line, while not neglecting it at all stages of the research.
The results that we obtained showed that the exit of the Zayzoun thermal station resulted in an increase in the loading of the transmission lines of the network by varying proportions 48%, and that the appropriate value of the network transmission angle is 22.50 leading to an improvement of the power factor of the transmitting terminal from 0.8 to 0.93, and an increase in the efficiency of the transmission line From (81-90)% and the high pass-through capacity of transmission lines to 995[MW], while the improvement of the inductive reactance led to an improvement in the deviation of percentile tension to 2.25%, a decrease in the distinctive impedance from (430-230) ohms and an increase in the pass-through capacity of the transmission lines to 1000 [MW].
