The article shows the urgency of the problem of studying resonant processes in extra high voltage power lines. The research of processes in extra high voltage power transmission lines is carried out to develop and implement measures to prevent overvoltages. Resonant overvoltages arising because of open phase modes of operation of the extra high voltage transmission line are considered. The paper shows the influence of the levels of longitudinal asymmetry on the calculation of the resistances of compensating reactors to reduce the values of overvoltages in the pause of single-phase automatic reclose. The degree of influence of the wire transposition scheme on the choice of the resistance of the compensation reactor and on the values of resonant overvoltages in the cycle of single-phase automatic reclose is considered. Estimation of asymmetry coefficients for different transposition schemes is performed. To select the resistance of the compensation reactor, the data of the existing high-voltage transmission lines of 750 kV were taken. Recommendations for the implementation of measures to prevent and limit resonant overvoltages are given. The current theoretical and practical problems of operation of the extra high voltage power line are considered and the ways of further research are shown. References 14, figures 5, tables 2.
Key words: asymmetric mode, resonance overvoltages, compensation reactor, transposition of wires, longitudinal asymmetry.
