Abstract
This paper presents an intensive analysis of the electric field resulting from the realistic high voltage ac systems existing in Kuwait. Two HV ac systems are modeled and analyzed. One is a 3-phase, double circuit, bundle conductor operating at 300 kV and the other system with an operating voltage of 132 kV. The electric field is calculated at the ground level to standardize the right-of-way (R.O.W) limits for those systems according to the maximum allowable electric field strength at the edge of R.O.W imposed by the staff regulatory. The analysis of two 3-phase, 300 kV, double circuit, bundle conductors transmission lines adjacent to each other and running in parallel is also conducted. The effect of the spacing between the two lines on the maximum gradient at ground level is evaluated to set values to the R.O.W limits for this realistic system. Graphs are presented for a simple evaluation of the R.O.W for any value of the maximum allowable electric field at the ground level. The charge simulation method (CSM), with complex charges and complex boundary conditions, is used to model the above mentioned systems with a great accuracy.
