文摘
The present work gives a model for ‘real-world’ high voltage transmission lines. The formulation of line parameters as a function of frequency takes into account the tower configuration, effect of earth conductivity and skin effect. The general transmission line problem is formulated in terms of partial differential equations. The Laplace transform offers a complete solution and has the advantage of reduced time requirements. Both switching and lightning surges can be simulated based on lines step response. The simulation is based on MATLAB software package, version 4.2b. Comparisons between field tests from Romanian 400 kV and computer results are presented.
