Evaluation of the application efficiency of the half-wave electric transmission line with a thyristor parameter stabilizer

The article assesses the efficiency of half-wave power transmission with intermediate power take-off and its implementation. The transportation of AC electricity over extremely long distances is possible using two fundamentally different methods, i.e. compensated and half-wave power transmissions. The former method involves compensated power transmission with power take-offs, which include reactive power sources located at the terminal and intermediate points of the line. The latter method uses half-wave and half-wave power transmission. The task of power selection from a half-wave power transmission is carried out using a thyristor parameter stabilizer. To conduct a comparative assessment of efficiency the capital costs for the construction of overhead lines and substations are compared for both transmission options, while other parameters are equal. The calculation is made according to the aggregated cost indicators of power lines and substations with a voltage of 35-750 kV, approved and recommended by PJSC FGC UES. The above calculations show that the cost of constructing overhead lines and substations for half-wave power transmissions with a thyristor stabilizer parameters is 11 % cheaper than the construction of compensated power transmission.
