Estimation of simulation accuracy of the electromagnetic compatibility near the power line

The questions of mathematical modeling of the electromagnetic field generated by the aerial power lines. The technique of definition of parameters of electric field on the basis of topological features of a transmission line. Shows how to replace the integral equations by a system of algebraic linear equations. The issues associated with numerical solution of integral Fredholm equation of the first kind obtained to determine the line charges in the conductive parts of high voltage electrical installations, in particular overhead transmission lines of alternating current. Justification of the choice of quadrature formulas when replacing the integral Fredholm equation of the first kind system of linear algebraic equations (SLAE). Comparative analysis and recommendations for choice of quadrature formulas depending on the number of calculated points and the accuracy of the solution. Evaluated the correctness of the solution of the integral equation of the first kind. According to the method of Lavrentiev regularization of the estimation error of the decision. Derive an expression to determine the optimal regularization parameter.
